Duplex Fasteners: Your Comprehensive Guide to Strength and Corrosion Resistance

Introduction

Ananka Group stands as an industry leader in the manufacture of Duplex Fasteners, offering a variety of size, grade, and spec high-quality Duplex fasteners. A manufacturer, stockist, supplier, and exporter, Ananka Group is focused on quality fasteners for demanding international industries from oil and gas to marine and construction applications. Duplex Fasteners are designed to withstand extreme strength and corrosion resistance conditions so that they can be used for demanding applications. We guarantee quality and strength throughout the range be it custom dimensions or specific grades, we get them to meet your particular needs in a project.

Duplex Fasteners are high-performance pieces made from duplex stainless steel, known for impressive strength and corrosion resistance. This structure of duplex stainless steel unites austenitic and ferritic structures with good mechanical properties and offers extreme durability even in very severe environment. Therefore, the applications where such conditions exist make Duplex Fasteners a favorite selection for oil and gas industry, chemical processing industries, marine applications, etc.

Duplex fasteners offer a much higher resistance to pitting and stress corrosion cracking as well as crevice corrosion, especially in chloride-rich environments, when compared with regular stainless steel fasteners. Their high strength-to-weight ratio also makes them quite popular for applications that involve high demand where weight saving and reliability are the word of the day.

More About Duplex Fasteners

Due to their unique properties, duplex fasteners are widely applied in a number of different industries. 

Here are a few key benefits that make them standout:

Resistance to Corrosion: High Chromium, Molybdenum, and Nitrogen make Duplex Stainless Steel resistant to pitting and crevice corrosion, especially in saline or acidic environments.

Strength: Duplex Fasteners have a higher strength than standard austenitic stainless steels such as 304 and 316. They are twice as strong as these grades and thus suitable for heavy-duty applications.

Temperature Resistance: The fasteners work efficiently at both low and high temperatures but perform more efficiently in moderately tempered temperature situations. They can tolerate the mechanical properties over a range of temperature without deformation.

Fatigue Resistance: The Duplex Fasteners' high strength along with ductility allows them to resist high-cycles stress, which enhances their fatigue resistance.

Cost-Effectiveness: Although the Duplex Fasteners will be more expensive when purchased, the long lifetime and the minimal maintenance means that they are the long-term cost-effective.

Specification of Duplex Fastener

The Duplex Fastener includes bolts, nuts, washers, screws, studs, etc. There are specifications of Duplex Fasteners based on their application, size, and design.

Following are some of the normal specifications:

Standard Grades :

Duplex 2205 (UNS S31803/S32205): Known for excellent corrosion resistance and strength.

Super Duplex 2507 (UNS S32750/S32760): Applied for a more extreme environment with higher resistance and strength

Diameter: M3 to M100 is available, but it is applied according to the usage.

Length: It depends on the application and type up to some meters in the case of threaded rods and studs.

Mechanical Properties

Yield strength is approximately 450-550 MPa in standard duplex, while for super duplex, it's 620 MPa and above.

Tensile Strength: 620–795 MPa.

Hardness: Duplex 2205 typically around 293 HB (Brinell Hardness) and up to 310 HB for Super Duplex.

Standards: Duplex Fasteners are usually manufactured under international standards such as ASTM, ASME, DIN, and EN to ensure the quality, reliability, and compatibility with other industrial parts.

Chemical Composition of Duplex Fasteners

The chemical composition is the main performance character for Duplex Fasteners and that includes strength, in addition to corrosion resistance. Here are two of the common duplex stainless alloys, whose composition is used for the fasteners, as presented below:

1. DUPLEX 2205/UNS S31803 / S32205

CR 21–23%,

NI 4.5–6.5%

MO 2.5–3.5%

N 0.08–0.20%

FE Rest

2. SUPER DUPLEX 2507/UNS S32750 / S32760

CR 24-26%

NI 6-8%

MO 3-5%

N 0.24-0.32%

FE Rest

High chromium and molybdenum content along with nitrogen makes these alloys resistant to localized corrosion such as pitting and crevice corrosion. This is very essential in offshore and other aggressive environments.

Applications of Duplex Fasteners

Duplex Fasteners are used in all applications where strength combined with corrosion resistance is a prerequisite. 

A few of the common industries and applications include:

Oil and Gas: Exploration, drilling, and refinery operations.

Chemical Processing: Equipment handling corrosive chemicals.

Marine Industry: Shipbuilding, docks, and underwater applications.

Construction: Structures exposed to harsh environments.

Water Treatment: Desalination plants, sewage systems, and chemical tanks.

Conclusion

Duplex Fasteners have found their place in industries demanding strength, durability, and corrosion resistance. Their exclusive properties make them suitable for harsh environments where both strength and resistance to multiple types of corrosion are equally balanced. Though the upfront cost is higher, the long-term savings are in the form of extended service life and minimal maintenance of Duplex Fasteners.

Everything you need to know about various types of Steel Flanges and their specifications for use.

The piping structure comprises various components that help to make their functioning smoother and more accessible. The pipes' mechanism works appropriately because many other devices and parts are attached to it that require work in coordination for the overall working of the piping structure. Flanges are one such component that exhibits excellent value to the piping structure. Flange is the component used for either attaching or removing two pipes together. Flanges create a space that is required between the two pipes so that they can be cleaned at regular intervals. Flanges are also essential for smooth transitions between two types of uneven lines. In this blog, we will learn about different types of Flanges-

1) Mild Steel Flanges Suppliers-

Mild Steel Flanges have significantly less carbon composition when compared to other Flanges. The mild steel flanges have a presence between 0.05 to 0.25% carbon composition. Mild Steel Flanges have been mainly and extensively used for the electric and automobiles industry in great numbers. Mild Steel Flanges suppliers specify the carbon contents to their customers and provide them with the best after-sales services.

2) Duplex Bolts and Flanges-

Duplex Bolts are not precisely like flanges but are the same as them in a smaller format. Duplex bolts are like nuts which are very small in size and are used for connecting all the components.

3) Hastelloy Flanges-

Hastelloy Flanges are circular in shape and have an elliptical opening from the middle, and the rest of the area is a flat surface. Hastelloy Flanges have good heat resistance and can sustain a high temperature, making them ideal for high-tensile work. Hastelloy Flanges also have excellent durability, making them one of the popular choices for flanges.

4) Stainless Steel 321 Flanges-

Stainless steel flanges have an alloy composition of chromium and nickel in them. They have excellent properties that make them strong against the corrosion that might occur due to weather changes. Stainless steel 321 Flanges are resistant to some other substances like chemical and organic chemicals that have been used extensively for many purposes. If there is a need to harden the stainless steel flanges, then it can only be done through cold working, and nothing related to heat will be impacted for the same. Uns s31803  is used for sterilizing the alloys and compositions for some flanges.

5) Stainless Steel 347 Flanges-

Stainless Steel 347 Flanges are advanced versions of the 321 ones. They have the highest endurance to temperature rises and are a mixture of Columbium and tantalum alloys composition in them. Stainless Steel 316 Fasteners are also one of the small components for these Flanges and are used for piping structures.

Above mentioned are some of the Flanges that are available in the market by the respective suppliers. While deciding which the best for your business is, one should consider all the factors well. This article helps you in knowing about the flanges better.
