ASTM 409 Stainless Steel Sheet

Stainless Steel Plate 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.  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 conten…
