Product Details

Product Introduction:
Stainless steel coil is an alloy steel with smooth surface, high weldability, corrosion resistance, polishability, heat resistance, corrosion resistance and other characteristics. It is widely used in various industries and is an important material in modern industry. Stainless steel is divided into austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and duplex stainless steel according to the structure state.

Cold Rolled Stainless Steel Coil

Austenitic Stainless Steel: stainless steel with an austenitic structure at room temperature. Steel contains Cr≈18%, Ni≈8%-25% andC≈0.1%. Steel has high toughness and plasticity, but low strength.

Martensitic Stainless Steel: A steel whose mechanical properties can be adjusted by heat treatment. It has different strength and toughness at different tempering temperatures.

Duplex Stainless Steel: Austenitic and ferrite each account for about half of the structure. When the C content is low, the Cr content is 18% to 28%, and the Ni content is 3% to 10%. Some steels also contain alloying elements such as Mo, Cu, Si, Nb, Ti, andN. This type of steel has the characteristics of austenitic and ferritic stainless steel.

Ferritic Stainless Steel: It contains 15% to 30% chromium and has a body-centered cubic crystal structure. This type of steel generally does not contain nickel, and sometimes contains a small amount of Mo, Ti, Nb and other elements. This type of steel has the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance, and excellent stress corrosion resistance.

Cold Rolled Sheet: Cold Rolled steel sheets are going to be the most refined versions. They will have a thinner presence while still being just as durable.
Hot Rolled Sheet: Hot rolled sheets are the most commercially viable choice on the market. They are factory produced and made to grade and then shipped out immediately. These are for quick production jobs or people going for the rustic look.
