Stainless steel plate is generally a general term for stainless steel plate and acid-resistant steel plate, which is an important metal material. The surface of the stainless steel plate is smooth, has high plasticity, toughness and mechanical strength, and is resistant to acid, alkaline gas, solution and other media corrosion. It is an alloy steel that is not easy to rust, but it is not absolutely rust free. Stainless steel plates have high temperature oxidation resistance, but the oxidation rate is affected by inherent factors such as the exposure environment and product form. Stainless steel plate because of its good corrosion resistance is widely used in medical, mechanical, chemical, metallurgy and shipbuilding and other fields.
