Stainless steel plate is a kind of alloy steel with smooth surface, high weldability, corrosion resistance, polishing, heat resistance and corrosion resistance. It is widely used in all walks of life and is an important material in modern industry. Stainless steel can be divided into austenitic stainless steel, ferritic stainless steel, martensitic stainless steel and duplex stainless steel according to the structure state. Austenitic stainless steel: stainless steel with austenitic structure at normal temperature. The 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: austenite and ferrite account for about half of the structure. When the C content is low, the Cr content is 18% ~ 28%, and the Ni content is 3% ~ 10%. Some steels also contain alloying elements such as Mo, Cu, Si, Nb, Ti and n. This kind of steel has the characteristics of austenitic and ferritic stainless steel. Ferritic stainless steel: containing 15% ~ 30% chromium, with body centered cubic crystal structure. This kind of steel generally does not contain nickel, and sometimes contains a small amount of Mo, Ti, Nb and other elements. This kind of steel has the characteristics of high thermal conductivity, low expansion coefficient, good oxidation resistance and excellent stress corrosion resistance.
