The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acid, alkaline gas, solution and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust-free. Stainless steel plate refers to the steel plate that is resistant to the corrosion of weak media such as atmosphere, steam and water, while acid-resistant steel plate refers to the steel plate that is resistant to the corrosion of chemical corrosive media such as acid, alkali and salt.
