Stainless steel sheet has a bright surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acid, alkaline gases, solutions and other media. It is an alloy steel that does not rust easily, but not absolutely rust-free. Stainless steel plate is a steel plate that is resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plate is a steel plate that is resistant to corrosion by chemically leaching media such as acid, alkali and salt. Stainless steel plate has been introduced since the early 20th century and has a history of more than one century.
