Stainless steel plate is the general name of the stainless steel plate and acid resistant steel plate. It has been more than 90 years since it came out at the beginning of this century. Its surface is bright and clean, has high plasticity, toughness and mechanical strength, and is resistant to corrosion of acid, alkaline gas, solution and other media. It is a kind of alloy steel that is not easy to rust, but not absolutely rust free. Stainless steel plate refers to the corrosion resistant steel plate in a weak medium such as atmosphere, steam and water, while acid resistant steel plate refers to the corrosion resistant steel plate in a chemical corrosive medium such as acid, alkali and salt. All stainless steel plates have high temperature oxidation resistance, but the oxidation rate is affected by inherent factors such as exposure environment and product morphology.
