Stainless steel sheets have a smooth surface and high plasticity, toughness, and mechanical strength. They are resistant to corrosion from acidic and alkaline gases, solutions, and other media. It is an alloy steel that does not easily rust, but it is not absolutely rust-proof. Stainless steel sheets refer to steel sheets resistant to corrosion from weak media such as atmosphere, steam, and water, while acid-resistant steel sheets refer to steel sheets resistant to corrosion from chemically corrosive media such as acids, alkalis, and salts.
