SV Stainless Steel: What are the grades of Stainless Steel Coils?

There are numerous applications for hot rolled stainless steel coils, including heating and cooling, appliances, automotive, and industrial equipment. The quality and strength of the final product will be determined by the grade of stainless steel used in coils.

Stainless steel is a great choice for many things, but it can also be used in a variety of ways when it comes to Coil Making. Grades of stainless steel are better suited for specific purposes, and with the proper techniques and tools, anyone can make quality coils using this metal. Furthermore, certain techniques can be used to improve the quality of the finished product.

Grades of Stainless Steel Coils:

Hot-rolled stainless steel coils are available in a range of grades based on the steel’s level of alloy content and quality.

Here are some grades for Stainless Steel Coils

SS 304

SS 304L

SS 316L

Duplex 2205

Duplex 31803

Duplex 1.4462

Duplex 317L

And plenty of others.

Duplex stainless steel coils are made from high-quality stainless steel alloys that have been heat-treated to make them resistant to wear and tear. Duplex stainless steel is created by mixing two distinct types of stainless steel, Ferritic and Austenitic. Ferritic stainless steel is more robust and resistant to extreme heat. Austenitic stainless steel contains a variety of alloys that makes the steel much more defiant to corrosion. They are also free from impurities, making them ideal for many heavy-grade applications.

Duplex 2205 stainless steel coils are made from alloys that have been heat-treated to a lower level of quality but still offer good resistance to wear and tear. Duplex 2205 is one of the most superior stainless steel grades in the market. It contains 22% chromium, 3% molybdenum, 5-6% nickel, and some amount of nitrogen. Duplex 2205 is more stress resistant, has zero to no corrosive response, maximum strength, and great impact toughness. They are also free from impurities, making them suitable for industrial applications.

The 300 series of grades, like 304, 304L, 316, and others are considerably less in quality but not less competent. These grades of steel are often used where corrosion resistance must not be the top priority and strength and flexibility are required. Each of these grades is corrosion-resistant and widely used in plenty of industries.

Types of Stainless Steel Coils:

Hot-rolled stainless steel coils are available in a variety of grades, depending on the level of steel content and the way the coil is cold-rolled. The grades can be divided into two categories: Hot Rolled and Cold Rolled.

Hot Rolled Coil:

Hot rolling means the steel rolling of coils with extreme heat. The steel coil is made to cool to room temperature. Cooling at high temperatures allows it to easily elongate the steel into sheets and coils but is not uniform. The internal stress is limited when compared to cold rolled steel. Hot-rolled steel is easily moldable and weldable, with increased elasticity and toughness. Hot rolled coils are applied:

Automotive Frames

Agricultural Equipment

Metal Buildings

Railroad Equipment

Construction

Beams

Cold Rolled Coil:

Cold Rolled Coil is similar to hot rolling, only the cooling down process is done by blasting lower temperatures at the rolled coil. Due to extreme cool down, the hardness of cold rolled steel is more and stronger than hot rolled clients. The finishing is better and is resistant to tension breaking. Cold rolled coils are used in:

Metal Furniture

Structural Parts

Home Appliances

Water Heater

Metal Containers

Fan Blades

Computer Cabinets

The hardness and corrosion resistance of stainless steel coils are also affected by their grade. As the grade increases, the steel becomes softer and is more corrosion-resistant.

Uses for stainless steel coils:

In addition to food storage, sporting goods, automotive and industrial components, and construction, hot-rolled stainless steel coils can also be used for a variety of other applications. The grades of stainless steel coils available on the market vary in terms of the quality of the steel, the processing and finishing techniques used, and the temperature range at which they can be used.

The higher the quality of the steel, the finer the grain, and the more uniform the thickness of the coil. Coils of higher quality grades can be used for applications that require greater accuracy, such as medical devices and sporting goods. Coils of lower-quality are less expensive but can be less accurate and require consistent thickness. Automobiles and industrial components are typical applications where they are not required to provide the highest degree of accuracy.

Hot-rolled stainless steel coils can be used in a variety of applications, including:

Food Preparation and Storage

Sporting Goods

Automotive and Industrial Components
