Stainless Steel Coils

The stainless steel coil is a type of metal coil made from stainless steel, which is a corrosion-resistant alloy of iron, carbon, and other elements like chromium, nickel, and molybdenum. The coil is typically manufactured through a process of hot-rolling, cold-rolling, or other forming techniques, which allow the stainless steel to be shaped into a thin, continuous strip.

The stainless steel coil is available in a variety of grades, each with its unique composition and properties. Some of the most common grades used for stainless steel coils include SS201, SS202, SS304, SS316, SS410, SS430, etc. The choice of grade depends on the intended application, as different grades have different levels of corrosion resistance, strength, and heat resistance.

Why and How Stainless Steel Resistant to Corrosion

The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal structure major role is chromium (Cr). Chromium has high chemical stability and can form a passivation film on the steel surface to isolate the metal from the outside. To protect the steel plate from oxidation, and increase the corrosion resistance of the steel plate. When the passivation film is broken, the corrosion resistance is lowered.

What Are the Different Specifications and Grades of Stainless Steel Coils?

Stainless steel is divided into several categories and each category is further divided into grades and series. The steel grade defines what type of steel and its composition and properties. While the grades reflect the specific alloy’s durability, quality, and temperature resistance, the numbers listed after the grade refer to its chemical composition, especially the chromium and nickel percentages. It plays an important role for fabricators, specialists, and customers to determine their requirement.

The most used grades of steel are the 200 series, 300 series, 400 series and duplex series. Moreover, 304, 304L, 316 and 316L stainless steel coils are the most popular and economical grades of stainless steels.

Surface Finishes For Stainless Steel Coils

Following is a list of the most popular finishes we supply, though others can be provided upon request.

• 2B. The most widely used surface finish, 2B gives a smooth, reflective grey sheen.

• 2D. Gives a low reflective matt finish.

• 2E. used to deliver a rough, dull finish.

• BA (Bright Annealed). Cold rolled and annealed in a carefully controlled atmosphere, BA allows the coil to retain a highly-reflective finish.

• HR (Hot Rolled). This is a scaled finish which is used where an aesthetically-pleasing final effect is not of key concern.

Benefits of Stainless Steel Coils

Corrosion Resistance - One of the primary benefits of stainless steel coil is its ability to resist rust and corrosion, making it suitable for harsh environments.
