The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions 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 steel plate resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plate refers to steel plate resistant to corrosion by chemically corrosive media such as acid, alkali and salt.

Stainless steel plate is generally a general term for stainless steel plate and acid-resistant steel plate. Coming out at the beginning of this century, the development of stainless steel plates laid an important material and technological foundation for the development of modern industry and technological progress. There are many kinds of stainless steel plates and steel plates with different properties. It has gradually formed several major categories in the development process. According to the organizational structure, it is divided into four categories: austenitic stainless steel plate, martensitic stainless steel plate (including precipitation hardened stainless steel plate), ferritic stainless steel plate, and austenitic plus ferritic duplex stainless steel plate. The main chemical composition or some characteristic elements in the steel plate are classified into chromium stainless steel plate, chromium nickel stainless steel plate, chromium nickel molybdenum stainless steel plate and low carbon stainless steel plate, high molybdenum stainless steel plate, high purity stainless steel plate and so on. According to the performance characteristics and use of the steel plate, it is divided into nitric acid resistant stainless steel plate, sulfuric acid resistant stainless steel plate, pitting corrosion resistant stainless steel plate, stress corrosion resistant stainless steel plate, high-strength stainless steel plate, etc. According to the functional characteristics of the steel plate, it is divided into low temperature stainless steel plate, non-magnetic stainless steel plate, free-cutting stainless steel plate, superplastic stainless steel plate, etc.
