Steel closets : voices of gay, lesbian, and transgender steelworker by Anne Belay, available on the Internet Archive

Transcript:

Miles began working in a steel mill in 1999 as an out lesbian, but he quit about eight years later because of repeated shoulder injuries and general exhaustion. He says it's not really accurate to say that he transitioned while working at the mill, since "we never really have a transition. We'll always be transgendered because our past experiences and history go along with us. So I'll always consider myself transitioning." I met Miles at the Cornwall Iron Furnace just outside of Philadelphia. It's a National Historic Landmark, pre- serving a nineteenth-century ironmaking complex and documenting the ironmaking process, as well as its effect on the area around the furnace and the workers' lives. Miles had suggested this meeting place, noting that he had always wanted to see the exhibits. He was curious about the history of the steelmaking process, and tickled by seeing his huge, powerful, mascu- line job echoed within this seemingly fragile incarnation made of bricks, and described for us by local elderly ladies.

For example, once the iron in Cornwall was molten, it was poured into one central branch, from which it flowed into a row of troughs pressed into the sand, which we were told resembled baby pigs nursing a sow-hence the name "pig iron." Miles noted that his job used many of the same tech- niques, since "I was a spruer. Parts will come out of a didion [a brand of metal separating equipment], which shook off the sand, and my job was to break the pieces apart. You see them come out on that long bar, they were lying them into them troughs, that's called a sprue tree, OK, as it goes down along, now in modern times, we have machines that press sand blocks together if you're work- ing on small parts. 'Cause we don't work on really big stuff, we work on cou- plings so it was smaller stuff. It would come down and this didion would spin it around, and little stars inside would clean off the material, but it still wasn't fully clean. It put them down on this table, which would shake up and down, and they were split in half, and the stuff would go and be remelted and what we wanted to keep for good pieces would go down and be cleaned and checked. I would stand there with a lead hammer and whack those pieces off the sprue tree. Separate the sprue tree from the good stuff." Seeing the shape of the sprue tree pressed into sand on the floor in front of a gigantic, prehistoric ladle made this whole process more comprehensible to me. And though the scale was much smaller than that of the big production mills still in op- eration, it was nonetheless vast-the blast furnace was about three stories high, with tap holes at the bottom from which the finished product ran.

The human component of steelmaking similarly remains fairly constant. After we examined a replica of a nineteenth-century steelworker dressed for work, Miles showed me his respirator, noting "The kerchief on the man's face? This would be more of a modern version of the kerchief." He also showed me his leather apron, adding that "they still use the [wooden] shoes, by the way. Nothing has really gotten up to date I guess you'd say. It's really an old art form. I would call it an art form." His burn clothes are made of Kevlar but oth- erwise duplicate the old patterns. This continuity is part of the cultural and historical context crucial to understanding how masculinity gets defined and shifted within the mills. The work remains the same, even though the larger culture's definitions of gender and masculinity are shifting. Count- less published accounts document the struggles of steelworker families when the man of the house is laid off and the woman has to find work. Though this shift occurred well after second-wave feminism, when most American women were in the paid workforce, the consistency of steelwork, and the corollary consistency of steelworkers' gender roles, made it hard for these families to adjust. Miles attributes his fascination with the consistency of mill work and mill workers over time to his experience with occupying both genders while working in the mills. Though he became a man, he did not change his tasks, his garments, or his self-presentation at work-he had always been masculine. Which parallels the "enormous struggle within the gay male community to come to terms with the stigma of effeminacy. The most strik- ing result has been a shift from effeminate to masculine styles" (Newton, Mother Camp, xiii). An exaggerated masculinity linked, if only rhetorically, to working-class culture, reinforces traditional gender roles, even as it sug- gests that only one gender is really worth doing.

Traditional to Innovative: Evolution of Steel Manufacturing in India

Steel is viewed as a pillar of modern civilization due to its wide usage today. Steel manufacturers in India play a significant role within the country and beyond and have evolved remarkably over the years. From the bloomer furnaces that were used in the past to the blast furnaces during the industrial revolution and today, the cutting-edge technologies, the evolution is immense.

In past times, steel production was labor intensive and typically consumed a lot of time due to the processes involved. These traditional methods were quite effective, but they had great limitations in terms of scalability. Over time, things have changed significantly, and the industry is no longer as it was in its infancy.

Traditional Methods

Steelmaking can be traced back to very many years ago, during ancient civilizations like the Egyptians. They discovered smelting practices for iron extraction. With time, different techniques were used to help refine steel and iron, including crucible steel and bloomery furnace process. The traditional methods used charcoal fuel widely. They were highly labor intensive, and only small quantities were produced. There wasn't much quality variation. This laid the foundation of the industry as we know it today, with the carbon steel producers playing a major role in shaping the industry.

The Bessemer Process During The Industrial Revolution Era

In the 18th and 19th centuries, steel production was revolutionized. This was due to the introduction of the Bessemer process in 1856. This was invented by Henry Bessemer, and it was a major milestone in steelmaking history.

The Bessemer process utilized air, which was blown through molten pig iron. The main intention here was to regulate the carbon content and remove impurities. With the adoption of this method, mass production of steel was possible at a lower cost. The process led to the creation of huge steel mills and blast furnaces. This led to the greatest growth in the steel industry that had not been witnessed before.

Electric Arc And Oxygen Furnaces

Later in the 20th century, another technology was introduced, propelling the industry further. The use of basic oxygen furnaces took the place of Bessemer converters. It became the primary method for processing molten iron into steel. Typically, oxygen was blown into the iron in a molten state to oxidize the impurities. This led to even higher-grade steel and faster turnaround rates.

Electric furnaces were introduced at the same time, and they helped recycle steel scrap. This meant lower reliance on ore.

Advanced Technologies

Spring steel strip coil suppliers and other players today rely on advanced steel manufacturing technologies. In the 21st century, advanced technologies have been widely adopted, improving efficiency and innovation. 3D printing or additive manufacturing is now one of the areas being exploited to create complex components using customized designs and intricate geometries.

C80 steel-grade suppliers and manufacturers now enjoy the results of automation and robotics used during manufacturing. This has led to safer, higher productivity, and access to a greater range of steel products in India.

Today, digitization initiatives leverage the Internet of Things, AI, and data analytics to optimize production schedules. It also aims to improve quality and monitor performance during steel production.

Sustainability

The best en8 steel grade suppliers look at the steel quality and sustainability. With the escalating environmental concerns taking center stage, sustainable practices are preferred over others. Alternative prices are now embraced to reduce the carbon footprint and energy consumption.

Steel manufacturers rely on carbon capture technologies and renewable energy options to mitigate the negative environmental impact in India. Recycling is also at the initiative's core, playing a role in waste production and conserving resources.

Embracing The Market Dynamics

In conclusion, it's important for steel manufacturers to embrace innovation to uphold sustainability and efficiency in the industry. Turning away from rudimentary technologies and choosing innovative options is one of the best ways to improve quality and reduce negative environmental impacts. Sustainability, automation, and digitalization are at the core of the industry and will keep shaping it in the future.

global top 25 companies accounted for 53% of total Iron Ore market(qyresearch, 2021)

Iron ore is a relatively abundant metallic element (it composes about 5% of the Earth’s crust) and the main raw material used in steelmaking. Around 98% of global mined iron ore is used to make pig iron, which is an intermediate product of the steel-making process. The remaining 2% is used in several applications, such as production of cement, printing inks, plastics, cosmetics (eye shadow), artistic colors, fertilizer ingredients, and pigments. Currently, iron ore is mined in over 50 countries; however, the bulk of production comes from Australia, Brazil and China.

Several minerals contain iron, but the primary sources of iron ore: hematite (Fe2O3), magnetite (Fe3O4), goethite (Fe2O3H2O) and siderite (FeCO3). The first three are of major importance because of their occurrence in large economically minable deposits. Iron ore rocks are usually rich in iron oxides and vary in color: rusty red, dark grey, bright yellow and deep purple.

Most of the iron ore resources are located in sedimentary rocks known as banded iron formations (BIF). Deposits may cover thousands of square kilometers and be hundreds of feet deep.

Typically, a deposit must contain at least 15-25% of Fe to be considered economically recoverable. Usually, tradable iron ore grades ranges between 58% and 66% of Fe content; however, a market of lower grades (sub- 60% Fe) does exist.

According to the new market research report “Global Iron Ore Market Report 2023-2029”, published by QYResearch, the global Iron Ore market size is projected to reach USD 208.24 billion by 2029, at a CAGR of -2.5% during the forecast period.

Secondary Refining Furnace

The steel refining process by secondary refining furnace can be divided into two categories: primary refining, aimed at removing carbon from pig iron, and additional refining processes conducted after primary refining, collectively referred to as secondary refining. Secondary refining furnace process involves the removal of impurities and adjustment of elements. The secondary refining usually takes place in a ladle (a transport container for molten steel) and is crucial for producing high-quality steel. The primary role of secondary refining is ultimate desulfurization, the elimination of oxygen, nitrogen, hydrogen, and other impurities, as well as the final decarburization of ultra-low carbon steel.

A steel melting and secondary refining method comprising the steps of melting steel manufacture raw materials while the molten steel is subjected to oxidation and decarburization so that the oxidation and decarburization are substantially completed before melt-down; after melt-down, heating the molten steel to a temperature above a liquidus line temperature and below 50℃. in temperature increment from the liquidus line temperature, and thereafter tapping the molten steel into a primary ladle; teeming the molten steel from the primary ladle into a secondary refining furnace; allowing the molten steel to be effluent into a secondary ladle at a lower portion of the secondary refining furnace while the temperature of the molten steel is raised; and continuously performing gas bubbling in the secondary ladle in a vacuum under existence of slag simultaneously with the effluence of the molten steel into the secondary ladle.

TYPES OF SECONDARY REFINING FURNACE

In the realm of steel production, the Secondary Refining Furnace stands as a pivotal player in achieving exceptional steel purity and quality. This crucial phase of the secondary metallurgy steelmaking process encompasses various techniques aimed at fine-tuning the composition of the molten metal, eliminating impurities, and ensuring the final product meets the stringent demands of modern industries.

The Manufacturing Process of HR Coil: A Comprehensive Guide

HR coil is a versatile and widely used steel product that serves as the foundation for a vast array of applications. Its manufacturing process involves a series of carefully controlled steps that transform raw materials into a high-quality, durable product. This guide delves into the intricacies of CR Coil Manufacturer, providing a comprehensive overview of each stage.

Raw Material Preparation: The journey of the HR coil begins with the selection and preparation of raw materials. Iron ore, the primary ingredient, undergoes a series of beneficiation processes to remove impurities and enhance its iron content. Subsequently, the iron ore is converted into pig iron, a semi-finished product, through a smelting process in a blast furnace.

Steelmaking: Pig iron, along with scrap steel and other additives, is charged into a basic oxygen furnace (BOF) to undergo steelmaking. Oxygen is blown through the molten mixture to remove impurities and refine the steel composition. The refined steel, now known as molten steel, is then tapped from the BOF for further processing.

Continuous Casting: Molten steel is transferred to a continuous casting machine, where it is continuously solidified into semi-finished slabs. The slabs are formed by passing the molten steel through water-cooled rollers, gradually cooling and solidifying the steel into long, rectangular shapes.

Reheating and Rough Rolling: The slabs undergo reheating in soaking pits to achieve a uniform temperature and enhance their plasticity. The heated slabs are then passed through a series of roughing mills, which reduce their thickness and elongate them into long strips.

Finishing Rolling: The rough-rolled strips enter the finishing mills, where they are further reduced in thickness and refined in surface quality. The finishing mills employ various rolling techniques, such as four-high and six-high mills, to achieve the desired thickness and surface finish.

Cooling: The hot-rolled coils are subjected to a controlled cooling process to achieve the desired microstructure and mechanical properties. The cooling method varies depending on the desired properties, ranging from air cooling to accelerated cooling using water or mist sprays.

Finishing Treatments: Depending on specific requirements, HR coils may undergo additional finishing treatments, such as:

Pickling: To remove surface scale and impurities, coils are immersed in an acidic solution.

Oiling: To protect the coils from corrosion during storage and transportation, a thin layer of oil is applied to the surface.

What is Alloy Steel and Composition, Types, Advantages, Disadvantages & Applications

Alloy steel is a type of steel alloyed with several elements such as molybdenum, manganese, nickel, chromium, vanadium, silicon, and boron.These alloying elements are added to steel to increase strength, hardness, wear resistance, and toughness. Metal alloying amounts might be anything between 1 and 50%. Alloy steels can be split into two groups: low alloy steel and heavy alloy steel. It is well known that low alloy and high alloy steel are distinguished by a 5% alloying component. Low alloy steel is technically equivalent to alloy steel in the oil and gas industry.

Alloy Elements in Steel

Here is a list of some of the most popular steel alloying elements, along with a description of each one's advantages.

Manganese:This is the alloying element that steel uses the most frequently. It increases toughness and tensile strength while reducing brittleness and the effects of sulphur.

Nickel: Corrosion resistance, hardness, and power are all increased by nickel. It also improves the low-temperature properties of steel.

Chromium: Chromium improves toughness, corrosion resistance, and abrasion resistance. In addition, it produces chromium carbides, which harden and strengthen steel.

Molybdenum: Molybdenum enhances toughness, high-temperature strength, and sliding resistance. It also enhances the outcomes of other alloying elements.

Vanadium:Vanadium increases strength, hardness, and wear resistance. In addition, it produces vanadium carbides, which harden and strengthen steel.

Silicon, boron, aluminium, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead, and zirconium are other alloying components used in steel.

Commonly used Grades of Alloy Steel Bars

When categorising alloy steel bars, the SAE-AISI system employs four-digit codes to designate the main alloying components and the carbon content. The alloy steel bar type 4140 has 0.40% carbon, 1% chromium, and 1% molybdenum. Several of the most popular alloy steel grades include:

4340:The steel alloy 4340 possesses outstanding toughness, fatigue resistance, and strength. Nickel, chromium, and molybdenum make it up. It is used in aeroplane landing gear, crankshafts, and other parts.

4140:Chromium-molybdenum steel 4140 possesses high levels of tensile strength, hardness, and wear resilience. It is utilised for components including gears, hubs, shafts, and bolts.

6150:tensile strength, hardness, and abrasion resistance are all well developed properties of chromium-vanadium steel 6150. It is utilised for springs, gearboxes, and other items.

8620:8620 steel is a nickel, chromium, and molybdenum alloy with a low carbon percentage and outstanding weldability. It is employed for carbureted components like gears and pinions.

Alloy Steel Manufacturing Processes

Chromium, nickel, molybdenum, vanadium, and other alloying elements are utilised in several alloy steel manufacturing processes. Different techniques are utilised to produce alloy steel depending on the type and grade of steel required. Some of the common processes include:

Electric arc furnace (EAF) process: Scrap steel or direct reduced iron (DRI), which is melted in an electric furnace, serves as the main feedstock for this process. The alloying components are added to the molten steel and refined by oxygen blowing or vacuum degassing. After that, the steel is shaped into slabs, ingots, billets, blooms, or other shapes.

Basic oxygen steelmaking (BOS) process: Liquid pig iron from the blast furnace and scrap steel serve as the main feedstock for this process, and impurities are oxidised by forcing oxygen into a converter. Before the steel is refined, the alloying elements are added via vacuum degassing or ladle metallurgy. After that, the steel is shaped into slabs, ingots, billets, blooms, or other shapes.

Electric induction furnace (EIF) process: In this process, discarded steel serves as the main feedstock and is melted in an induction furnace utilising electromagnetic induction. After the alloying components have been added, the molten steel is refined using ladle metallurgy. After that, the steel is shaped into slabs, ingots, billets, blooms, or other shapes.

Crucible process: This process melts ferroalloys, steel scrap, and wrought iron in an airtight crucible using charcoal as the fire source. The proportion of carbon and alloying elements is controlled by the feed substance's composition. The steel is melted and then cast into ingots.

Bessemer process: The main feedstock for this process is pig iron, and the air is forced into a converter with a pear-shaped form to oxidise the impurities. By incorporating ferromanganese or spiegeleisen, a pig iron with a high manganese content, into the molten steel, one can control the alloying elements and carbon content. The steel is melted and then cast into ingots.

Open hearth process: The main feedstocks used in this process are pig iron and scrap steel, which are melted in a shallow hearth with gas or oil as fuel. To control the alloying and carbon content, elements such as limestone, iron ore, and others can be added to the molten steel. The steel is melted and then cast into ingots.

The alloy steel ingots, blooms, billets, or slabs are further treated after casting to produce a variety of alloy steel products in different shapes and sizes, such as bars, rods, wires, sheets, plates, pipelines, and tubes. The forging process, hot rolling, cold rolling, machining, heat treatment, and surface treatment are other processing techniques.

Types of Alloy Steel

Let's now check a few common types of alloy steel.

Low Alloy Steel

Low-alloy steel is a type of steel that has, in terms of weight, less than 5% of alloying elements such as chromium, nickel, molybdenum, vanadium, etc. Low-alloy steel offers more robust mechanical properties than regular carbon steel, such as hardness, toughness, wear resistance, and corrosion resistance. The term "4130 steel" refers to a typical low-alloy steel having 0.30% carbon, 1% chromium, and 1% molybdenum.

High Strength Low Alloy (HSLA) Steel

High strength low alloy (HSLA) steel has greater mechanical properties and is more resistant to atmospheric corrosion than normal carbon steel. Because they are created to meet mechanical criteria rather than chemical requirements, these steels are distinct from "normal" alloy steels.

High Alloy Steel

A high concentration of alloying elements is what distinguishes high-alloy steels. The most widely used high-alloy steel has a least 12% chromium content and is called stainless steel. Austenitic, ferritic, and martensitic stainless steel are the three main varieties. High alloy steels are utilised in applications requiring significant strength and corrosion resistance, such as aerospace and defence components, chemical processing equipment, and medical implants. High-grade steel includes materials like stainless steel, tool steel, and maraging steel.

Stainless Steel

Rust and corrosion are not easily absorbed by the iron alloy known as stainless steel. In addition to the required 11% chromium concentration, it may additionally contain substances like carbon, other non-metals, and metals to attain other desirable qualities. Precipitation-hardening steels, austenitic, ferritic, martensitic, and duplex steels make up the majority of the stainless steel family. Usually austenitic steels, which can also have up to 35% nickel and up to 26% chromium, are the most corrosion-resistant steels.

Microalloyed Steel

Microalloyed steel has trace levels of alloying materials like boron, zirconium, niobium, vanadium, titanium, and rare earth metals in the range of 0.05 to 0.15%.  They are used to enhance precipitation hardening or the microstructure of the particles. Microalloyed steels produced by controlled rolling are an ideal choice for many engineering applications due to their moderate strength, moderate toughness, excellent toughness and fatigue strength, and simplicity of welding.

Advanced High Strength Steel (AHSS)

Advanced high-strength steel (AHSS), a type of steel, is mostly utilised in sheet form for automobile structures. This classification's steel types initially had multiphase microstructures with ferrite serving as the primary phase. However, more recent grades have solely relied on austenite or martensite. New generations of steel grades called advanced high-strength steels ensure that steel parts and components adhere to fundamental safety and efficiency standards while yet being inexpensively and easily fabricated.

Maraging Steel

Famous for having high strength and hardness without compromising ductility is a type of steel known as maraging steel. The name "maraging" derives from the words "martensitic" and "ageing," which refer to the method of extended heat treatment. Usually, a number is used to designate the nominal tensile strength in thousands of pounds per square inch (ksi), which is used to describe maraging steels (for example, SAE steel grades 200, 250, 300, or 350). The US military standard MIL-S-46850D1 specifies the compositions and essential qualities.

Maraging steels have high levels of toughness, moderate corrosion resistance (similar to that of standard martensitic steels), ultra-high strength, a simple ageing process that minimises distortion, good machinability (typically in the annealed state), and good weldability.

Tool Steel

Tool steel is a particular type of steel that is ideal for use in the production of tools and tooling, including cutting tools, dies, hand tools, knives, and other items. Using tool steels, metals and other materials can be cut, pressed, extruded, and coined. Because of their resistance to abrasion, tool steels are essential for tooling. For instance, injection moulds require tool steels because their endurance enables for hundreds of thousands of moulding operations over the length of a mould's lifetime.

Tool steels are made up of different amounts of carbide-forming metals like chromium, molybdenum, tungsten, and vanadium. These iron-based alloys have comparatively high carbon concentrations for strength and carbide production. For high-temperature strength, substitutional solutes like nickel and cobalt are added.

Alloy Steel Properties 

A particular kind of steel called alloy steel is created by incorporating trace amounts of other elements or alloys into pure carbon steel. In general, alloy steels are stronger, harder, and more resistant to wear than pure carbon steel. The steel is alloyed with the alloying elements to enhance one or more of its mechanical and/or physical characteristics, including toughness, toughness, high-temperature performance, corrosion resistance, and wear resistance.

Alloy Steel Applications

Alloy steel is utilised in a wide range of items, from basic hand tools and cutlery to exceptionally demanding applications like the turbine blades of aviation engines and nuclear reactors. Typical applications for alloy steel include:

Building Structures: The skeletal frames of stadiums, skyscrapers, airports, and bridges are made of alloy steel.

Building Bridges: In the building of bridges, alloy steels are utilised. They are made of alloying metals like nickel, copper, and chromium.

Flat products: Premium alloy steel is utilised to create the flat slabs and strips that are used for welding in the construction sector.

Coil Products: Alloy steel sheets can be galvanised in addition to being rolled hot or cold by immersing them in hot water. These hot-dipped galvanised coils are used to create building materials like side rails, light steel frames, roof purlins and lintels.

Automotive: Alloy steel can be used to make crankshafts, axles, gears, and other motor parts.

Alloy Steel Advantages

In alloy steel with normal carbon steel reveals a number of advantages.. 

One of alloy steel's most significant advantages is the enhanced strength and endurance of the material. This makes it ideal for activities needing a lot of power, such as running heavy machinery or building bridges.

Furthermore, alloy steel is far more durable than typical carbon steel. This is because alloy steel has a variety of alloying components, which give it greater weather resistance than typical carbon steel. As a result, it can be used outside without being concerned about rust or other damage caused by moisture or exposure to the environment.

Another advantage of alloy steel is that it welds more easily than traditional carbon steel.

Alloy Steel Disadvantages

The disadvantages of alloy steel are numerous as well.

One of the biggest disadvantages of alloy steel is the fact that it is more expensive than carbon steel.

Alloy steel is also less bendable than carbon steel.

Additionally, alloy steel melts at a lower temperature than carbon steel.

Furthermore, alloy steel requires more effort to process than carbon steel. However, alloy steels are resistant to corrosion.

Examples of Alloy Steel

Some examples of alloy steel are:

Nickel Steel: an alloy steel with a significant nickel content. It is renowned for its extreme hardness and strength.

Manganese Steel: a kind of alloy steel with a significant manganese content. It is renowned for its exceptional wear resistance and impact strength.

Chromium: a chromium and molybdenum-containing kind of alloy steel. It is renowned for its excellent strength and resistance to corrosion.

Steel prices are expected to rise – Stainless Espresso

Steel prices are expected to rise again soon. This is the increasing opinion of analysts. In addition, the Chinese steel province of Tangshan is now imposing production restrictions of 50% to counter air pollution. Competition between high grade and low grade nickel and stainless steel scrap is growing, which is likely to lead to rising raw material prices. And Indonesia is increasingly criticised for massively increased CO2 emissions and trade restrictions.

Steel prices are expected to rise

Steel futures prices continued their upward trend, supported by ongoing production restrictions in Tangshan, China’s leading steelmaking centre. According to reports, Tangshan has asked 11 A-rated steel mills to proactively reduce production, while B-rated and lower-rated mills will have to shut down 50% of their sintering facilities from 1-31 July due to deteriorating air quality. In addition, several Chinese steel producers have announced maintenance plans for July, following similar patterns in previous months.

These actions contribute to the latest expectations of Asian analysts of reduced supply in the steel market, thereby supporting steel prices. Steel benchmarks for rebar rose by 0.78%, hot-rolled coil by 0.89% and wire rod by 0.45% on the Shanghai Futures Exchange (SHFE).

Competition between high grade nickel vs. low grade nickel is increasing

The competition between the different nickel grades is expected to pick up speed soon. As already announced in early June 2023, Indonesia has a growing problem with the availability of low grade nickel ore and intends to limit the production of e.g. nickel pig iron in order to save the valuable raw materials for higher grade products.

Indonesia needs more raw materials for grade 1 nickel

According to media reports, production capacities of about 200,000 MT of Class 1 nickel should be completed in Indonesia by the end of 2024. Which also explains why there needs to be a shift of raw materials between different producers.

Electromobility needs nickel

On the one hand, this could lead to a relief in the strongly growing market for electromobility, which had recently reduced inventories on the commodity exchanges significantly and partly dropped to historic lows. On the other hand, however, this will reduce the supply of nickel pig iron, which is used in the production of stainless steel.

China plans to use more than 8.3 million tonnes of stainless steel scrap by the end of 2025

At the same time, China plans to increase the share of scrap in stainless steel production from the current 21% to 26% by the end of 2025 – an increase of almost 1.6 million tonnes of stainless steel scrap per year. This will significantly reduce the availability of nickel-bearing scrap and cause prices to rise worldwide.

Competition between high grade, low grade and scrap will therefore increase in the future. What could possibly lead to relief in the EV sector, however, is likely to lead to higher raw material costs in the stainless steel sector – because NPI will become scarcer and scrap will be in greater demand.

Indonesia has become the world’s sixth largest emitter of CO2 from fossil fuels

Even though Indonesia has emerged as the largest producer of nickel products, it comes at a high price. According to recent reports, Indonesia has become the world’s sixth largest emitter of CO2 from fossil fuels in 2022. And there is no end in sight to the burning of coal in the Asian country.

Indonesian Class 1 nickel needs a lot of energy

This poses problems for Indonesia in terms of nickel production. This is because the nickel-bearing laterite ore, which is mainly found in Indonesia, needs much more energy to be converted into class 1 nickel. This means that CO2 emissions are up to six times higher than in Canada, Russia or Australia, for example, where mainly nickel-bearing sulphide ore is mined and processed.

WTO, IMF, EU: Indonesia has to put up with a lot of criticism

Indonesia recently had to put up with a lot of criticism from the World Trade Organisation (WTO) and the International Monetary Fund (IMF) about the export bans imposed or planned by Indonesia on raw materials (e.g. nickel or bauxite). With the new EU regulations on deforestation-free products, another construction site for the Indonesian economy had already opened up in May 2023.

The excessive use of fossil fuels in Indonesia’s energy mix is now likely to raise further criticism with regard to e.g. the EU Carbon Border Tax CBAM and CO2 certificate trading in Indonesia. And raise the legitimate question: When will Indonesia get a grip on this?

What markets have Ukrainian steelmakers (temporarily) lost?

Last year, Ukrainian metallurgy faced numerous challenges resulting in a three-fold decline in production. These challenges included factory shutdowns and occupations, electricity and working capital shortages, decreased demand, and complex logistics. The last factor is probably the most important. With the majority of steel products being exported by sea (80%), the blockade of Black Sea ports not only caused a three-fold reduction in export volumes but also resulted in the loss of foreign markets. Simultaneously, imports have become increasingly significant for domestic consumption due to product shortages, as the factories in Mariupol were the sole producers in Ukraine.

This year, Ukrainian producers are forced to build their production and sales strategies taking into account both the blocked ports and the global market conditions, which are not too optimistic. Moreover, companies are facing new challenges, such as water shortages due to terrorist attacks by the aggressor country.

The full-scale invasion by russia profoundly impacted Ukraine’s foreign trade activity, causing a decline in key indicators (Figure 1). The export of steel products, typically amounting to several tens of million tons, experienced a three-fold decrease. Nevertheless, the majority, approximately 80%, of the products manufactured by Ukrainian metallurgists continued to be exported as before.

Figure 1. Export, import, and consumption of steel products in Ukraine, million tonnes

Source: Ukrmetalurgprom, State Customs Service of Ukraine data, and expert assessments.

This article’s analysis of foreign trade considers goods of group 72 (“Iron and steel”) and commodity items 7301-7306 of group 73 (“Articles of iron and steel”) of the Commodity Nomenclature of Foreign Economic Activity (CN FEA) to be metal products or steel. Domestic consumption does not include raw materials (pig iron, scrap, ferroalloys), with data for 2022 being expert assessments. 

Prior to the full-scale invasion, Ukraine’s imports of steel products surpassed 1.3 million tonnes, accounting for approximately a quarter of the apparent consumption (which includes both production and imports but excludes exports) in the domestic market. However, last year, the volume of imports decreased by half, yet its proportion in domestic consumption rose to one-third.

The decline in imports and domestic consumption can be attributed to two primary factors: constrained logistics and reduced demand for rolled steel due to a slowdown in economic activity caused by the occupation of territories, active hostilities, russian attacks on critical infrastructure facilities, and population migration abroad.

Export of steel products from Ukraine

Semi-finished products and pig iron (as shown in Figure 2) constitute approximately half of the product structure in the export of metal products. These products are generally less lucrative compared to finished rolled steel, which finds applications in various sectors such as construction, automobile and machine building, the oil and gas industry, and more.

Before the full-scale invasion, manufacturers were motivated by supplying semi-finished products to their own assets abroad and responding to market conditions. However, last year, the situation shifted to a “survival” mode, where companies focused on supplying the products they were capable of producing and shipping. For instance, during periods of power outages in the fall, mills reduced the production of rolled steel, which is energy-intensive, and instead prioritized smelting pig iron, which relies more on gas.

A substantial portion of the supply consists of the export of flat-rolled products. However, the volumes of these exports have declined because the main producers of such products are the Metinvest Group’s plants in Mariupol, which are currently occupied.

Last year, positive changes were observed as well. The suspension of import duties in the USA and the rise in prices for pipe products, which carry a significant added value, contributed to an increase in their share within Ukraine’s exports from 3% to 6%.

Ukraine’s export of steel products extends to nearly all continents worldwide (as depicted in Figure 3). The companies operating in “normal” mode during the first two months of 2022 (accounting for 43% of the total volume of steel products for the year) helped maintain the existing geographical presence of Ukrainian manufacturers by the end of the year. However, there was a noticeable decline in the number of countries receiving Ukrainian exports, decreasing from 98 in the first quarter of 2022 to only 62 in the fourth quarter.

Figure 3. Geography of exports of Ukrainian steel products in 2022, tonnes

Note. Almost the entire volume of exports to russia was sent in the first quarter of 2022, with a small cargo shipped in September. Officially, exports to the russian federation were banned at the end of September 2022.

The decrease in volumes of metal product exports had an impact on all sales regions, spanning from Europe to the distant Pacific region (as depicted in Figure 4). The extent of the decline varied based on the distance the cargo had to traverse to reach the buyers, considering the logistical challenges involved. As a result, the presence in remote destinations nearly vanished due to these circumstances.

Figure 4. Regional structure of export of Ukrainian steel products, tonnes

Source: International Trade Center

The regional distribution of countries has been conducted according to the classification of the World Bank.

Specifically, exports to Southeast Asia and Oceania experienced a tenfold decline, while exports to Latin America dropped by 8.5 times, given the disrupting traditional transportation routes. Furthermore, supplies to African countries located south of the Sahara Desert witnessed a decrease of over sixfold.

The situation in the Middle East and North Africa differed somewhat as exports to this region experienced a decline of 3.5 times against the backdrop of the blocked traffic through the Black Sea and the absence of Mariupol mills among the suppliers. Ukraine exported 79% of last year’s volume to this region during the first quarter.

In terms of export volumes, North America stands as the second-largest destination for Ukrainian exports. Last year, sales to this market experienced a relatively smaller decrease of 2.6 times. Similar challenges were encountered, including logistical limitations, the absence of Mariupol suppliers, and reduced production in territories under Ukrainian control. However, Ukrainian companies partially adjusted their shipping routes by diverting exports from Black Sea ports to European ports. This adaptation allowed for an increase in the export of some goods. For instance, Ukrainian manufacturers of seamless pipes witnessed a 21% year-on-year increase in their exports to the USA thanks to the suspension of import duties.

Despite the decrease in supply volumes by 2.6 times, Europe and Central Asia continued to be the primary consumers of Ukrainian steel products. Remarkably, their share expanded to 72% since Ukrainian manufacturers redirectied trade flows through land and river transportation to neighboring countries.

The European Union emerged as the primary destination for Ukrainian exports, with its share in the total volume of Ukrainian steel exports rising from 35% in 2021 to 57% in 2022. In the second half of last year, this share further increased to 90%. Several factors contributed to this shift. Firstly, the blockade of the Black Sea compelled Ukrainian manufacturers to redirect trade flows towards neighboring countries, particularly Poland (which saw a 7% increase in exports from Ukraine). Secondly, the European Commission suspended trade protection measures on Ukrainian products. Lastly, exports to russia, which was one of Ukraine’s top five largest trade partners, were minimized during this period.

The global metallurgical industry has been grappling with excess production capacity in recent years, primarily due to establishing new production facilities in Asia and the Middle East. Consequently, the disposal of Ukrainian volumes does not pose a critical problem for international consumers, as alternative suppliers can readily replace them.

Partial compensation of Ukrainian volumes occurs through regional trade. Moreover, Asian manufacturers are taking a more prominent role and strengthening their positions in the Middle Eastern and European markets. For instance, in the segment of semi-finished and finished steel products, volumes that were previously supplied by Ukraine and partially by russia have been replaced by Asian producers (as shown in Figure 5). This trend has been ongoing and continues in the current year.

Figure 5. Geographical structure of steel imports in the EU-27, %

While Asia is currently stepping in to replace the volumes previously exported by the damaged Mariupol facilities, it may face challenges in the long run. Several important points should be considered. Firstly, despite the lower production costs, transportation expenses from Asia to Europe need to be taken into account. Secondly, import quotas are in place, limiting the volume of shipments from Asian producers. As a result, they may not be able to exceed these established quotas. Lastly, the European Union is increasingly moving towards green metallurgy.

Considering Europe’s decarbonization targets, it is expected to be extremely challenging for most Asian producers, such as China and India, to achieve carbon neutrality even in the medium term. In contrast, Ukraine has an opportunity to “rebuild better” after the war and transition to a new green technological level. This shift aligns with the goals of sustainable development, as emphasized by experts and steelmakers.

Presently, the primary diplomatic efforts are focused on including metallurgical products in the grain agreement and enhancing the transportation infrastructure in Ukraine and Europe. This involves initiatives to improve railways, transshipment hubs, checkpoints, and port infrastructure.

Import to Ukraine

Most imports of steel products to Ukraine are made up of goods that are either not produced in the domestic market or do not meet the quality/pricing requirements of consumers. Primarily, this includes flat-rolled products: its share in imports previously exceeded 50%, and in 2022, it increased to 69% (Figure 6). Before the invasion, mainly coated flat-rolled products were imported as the domestic producers could not fully meet the demand. The need for hot-rolled flat products, which used to be produced by Mariupol-based plants, also increased, given that Zaporizhstal, the only producer of these products at present, was operating intermittently due to a shortage of electricity. Additionally, the import of products previously solely produced by Azovstal, such as beams and rails, has increased.

Figure 6. Commodity structure of steel imports to Ukraine, %

Source: State Customs Service of Ukraine

Until last year, the major steel exporters to Ukraine were russia, China, and Turkiye, accounting for over half of the import volumes. However, for obvious reasons, russia lost its position when an import embargo was imposed in April 2022. Imports from Turkiye also decreased by 20%. Nevertheless, Turkish producers emerged as the primary source of rolled steel for Ukraine in 2022, and by the fourth quarter, import volumes reached pre-invasion levels. Purchases from China experienced a significant decline of 61% due to logistical challenges. Like Turkiye, China meets Ukraine’s demand for flat rolled products, particularly coated rolled products used in construction (e.g., corrugated board), automobile manufacturing, and household appliances. However, the inflow of Chinese coated rolled products may further decrease if new anti-dumping duties on this product are established in Ukraine.

Figure 7. Geography of steel product imports to Ukraine in 2022, tonnes

Similar to the export segment, European countries have played a supportive role in supplying steel products to Ukraine by increasing trade flows. Slovakia has emerged as the third-largest exporter to Ukraine, while the volume of supplies from Romania has nearly quadrupled. Notably, Romania has been able to establish the supply of scarce products, specifically flat-rolled products, to Ukraine.

Where does the situation stand this year?

There are currently no official detailed statistics for the first five months of 2023, but the main trends can be seen.

Firstly, the stabilization of the electricity supply situation in February resulted in increased production volumes for Ukrainian manufacturers. Thus, in March, crude steel steel production increased by almost a quarter compared to February, while rolled steel production grew by 30%, according to the according to Ukrmetallurgprom. The upward trend continued in April and May.

Overall, both for the first quarter and the first five months of the year, operating results remain significantly lower than last year’s volumes, given the high comparison base of January-February 2022, but Ukraine has increased production compared to the last quarter of last year.

Secondly, steel imports also increased, given the increased consumption in the domestic market (Figure 7) ahead of the construction season and due to disruptions in the operation of local steelmaking companies in winter.

Figure 8. Quarterly volumes of Ukrainian exports and imports of steel products, tonnes

Thirdly, the reorientation of all export goods to the western border, primarily agricultural products and iron and steel, has led to significant competition among exporters and increased queues at the borders due to limited capacity. 

In such a situation, a temporary restriction on grain imports from Ukraine to certain EU countries could help boost exports of mining and steel products by reducing congestion at the borders and provided that the price situation on the iron ore and steel products markets is favorable. In addition, railroad transportation is also declining due to the unstable operation of the grain corridor. According to April’s operational data, export transportation of goods by rail decreased by 8% compared to March due to a decrease in grain shipments (-15%). However, export transportation of metal products increased by 16%. In May, export rail transportation of ferrous metal products continued to grow to almost 0.5 million tonnes, while grain transportation almost halved.

At the same time, the terrorist attack on the Kakhovka hydroelectric power plant is becoming a new challenge for the Ukrainian steel industry. For example, Kryvyi Rih’s water supply was 70% dependent on the Kakhovka reservoir, so ArcelorMittal Kryvyi Rih, the largest steel producer in Ukraine, stopped steelmaking and rolled steel production to minimize water consumption. At the time of publication, the company has not resumed production. Nikopol Ferroalloy Plant was also forced to cut production.

Conclusions 

The data shows not only a reduction in the volume of Ukrainian steel products exported abroad in 2022, but also a forced reduction in the markets of presence. As steel cannot be shipped through traditional ports such as Pivdennyi, Mariupol, Odesa, Mykolaiv, etc., companies have shifted to using railways, Danube river ports, and European seaports, and focused on the closest possible markets – European countries. As a result, producers have reduced cooperation with regions with longer transportation routes.

It is difficult to predict how long Ukrainian producers will be limited in their export opportunities, given the ongoing war and the need for additional financial resources and time to develop transport infrastructure. This is in addition to the issue of rebuilding assets in the temporarily occupied territories. Ukraine plans to establish new joint railroad checkpoints on the border with the EU in 2023-2024 and to develop the railroad by repairing, modernizing, and laying new tracks. In turn, European partners, such as Poland, through whose ports Ukrainian mining and metals products were shipped, plan to expand the capacity of the Gdansk port by 50% by 2025.

In addition, the following factors are worth paying attention to. The shift to shipping Ukrainian products by rail instead of sea has led to a multiple increase in transportation costs. Consequently, in times of declining steel prices on international markets, high transportation costs make our products less economically attractive, as the share of logistics costs increases. According to industry analysts and the National Bank of Ukraine, iron ore and steel prices will continue to decline in the second and third quarters of this year, which may put pressure on the competitiveness of Ukrainian suppliers.

Moreover, even as new logistics routes are being established, Ukrainian producers are facing weaker demand for steel products in key markets, particularly in Europe, which also limits their plans to increase production. This was stated by Mauro Longobardo, CEO of ArcelorMittal Kryvyi Rih, at the international conference “Onwards and Upwards: Reforming Ukraine During the War” held on May 19 in Kyiv.

In addition, the prospects for increasing steel production in Ukraine may be limited again due to a drop in electricity supply. In particular, there is a risk of electricity shortages in the summer, which may force the industry to either cut back on electricity consumption or import more expensive energy from Europe. 

Last but not least, water shortages at enterprises in the Dnipropetrovsk region that rely on the Kakhovka reservoir may become another challenge along with electricity shortages.

As for imports, it will continue to grow and account for an important share of domestic consumption until Ukraine resumes production of deficit goods. Russia has ceased to be the main supplier of steel, being replaced by Turkiye, European countries, and, in some commodities, China.

What Do You Know About Still Mill?

A steel mill, which is also referred to as a steel factory, is an industrial site dedicated to manufacturing steel. It can take the form of an integrated steel plant that engages in all aspects of steel production, from extracting iron ore to creating finished products. Alternatively, as an expert at GMB Heavy Industries says, it can be a plant that specializes in producing semi-finished casting products made from molten pig iron or recycled metal scraps. If you want to learn more about still mill, keep reading.

The production and refinement of steel involve a range of techniques and processes, such as shaping using cold rolling methods, machining (such as drilling), joining through welding, and coating with materials like zinc, as well as heat treatment, which often involves tempering the steel to improve its properties. Additionally, surface treatment, such as carburizing, is also commonly employed to enhance the quality of steel products.

How Is the Process Done?

There are two main methods of steelmaking: primary and secondary. 

Primary steelmaking involves either the basic oxygen steelmaking (BOS) process or the electric arc furnace (EAF) method. In the BOS process, recycled scrap steel is added to molten iron, and then oxygen is blown into the mixture at high temperatures to lower the carbon content. In the EAF method, recycled steel scrap is melted using high-power electric arcs at temperatures of up to 1650°C to create high-quality steel.

Secondary steelmaking combines these two processes to refine the composition of the steel being produced. Specific elements are added at precise temperatures and within controlled environments to create the desired composition. Methods used for these controls include stirring, ladle furnaces, ladle injections, and degassing.

Steel mills offer several advantages, including:

Versatility: Steel is a versatile material that can be used in a wide range of industries, from construction to automotive to consumer goods. This versatility makes steel mills an important contributor to many aspects of modern life.

Cost-Effective: Steel production is often more cost-effective than other materials due to the abundance of raw materials and the efficiency of the production process.

Strength and Durability: Steel is known for its strength and durability, making it an ideal material for construction and infrastructure projects.

Recyclability: Steel is a highly recyclable material, with a recycling rate of over 90%. This makes steel mills an important part of the circular economy, reducing waste and conserving resources.

Technological Advancements: Steel mills are constantly evolving and improving their processes, leading to advancements in technology and innovation. This can lead to improvements in the efficiency and sustainability of the steel production process.

Job Creation: Steel mills are often major employers in the communities where they are located, creating jobs and driving economic growth.

Is Still Mill Eco-friendly?

Steel has a minimal environmental impact compared to other materials since it does not release harmful toxins or chemicals. Furthermore, magnets can easily recover steel from the environment, making it a sustainable material. In addition, steel production does not result in toxic run-off, further reducing its negative environmental impact.

In the fourth quarter of 2022, Hot Rolled Coil prices in the US market showed a mixed trend due to weakening demand amidst a few positive signs in the market. As steelmakers approached or even met breakeven points, multiple market participants recognized that the Hot Rolled Coil market had reached a bottom in October. High-priced raw materials had higher conversion costs, mainly expensive pig iron inventories and higher-priced scrap inventories. With the Thanksgiving holiday in the United States in November, demand plummeted, and the rest of the year was expected to be slow. However, Hot Rolled Coil prices recovered in December. According to suppliers, HRC spot prices fell in mid-December as the market remained quiet due to the Christmas holiday. On the other hand, steel mills had maintained higher prices and were refusing to lower them. Domestic Hot Rolled Coil manufacturers in the US market appeared optimistic about the new year, but spot pricing remained lower than during the previous summer and fall seasons. Thus, the HR Coil (3 mm) prices for Ex-US Midwest (USA) were fixed at USD 784/MT during the last week of Q4.
