Austenitic Stainless Steel : stainless steel with an austenitic structure at room temperature. Steel contains Cr≈18%, Ni≈8%-25%and C≈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, and N. Thistype 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.
