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.
