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 does not rust easily, but not absolutely rust-free. Stainless steel plate refers to a steel plate that is resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plate refers to a steel plate that is resistant to corrosion by chemically corrosive media such as acid, alkali, and salt. Stainless steel plate has a history of more than 1 century since it came out in the early 20th century.

Stainless steel plate is generally a general term for stainless steel plate and acid-resistant steel plate. Stainless steel plate refers to a steel plate that is resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plate refers to a steel plate that is resistant to corrosion by chemically corrosive media such as acid, alkali, and salt. Since the advent of stainless steel plates at the beginning of this century, the development of stainless steel plates has laid an important material and technical foundation for the development of modern industry and scientific and technological progress. There are many types of stainless steel plates with different properties. It has gradually formed several categories in the development process. According to the structure, it is divided into four categories: austenitic stainless steel, martensitic stainless steel (including precipitation hardening stainless steel), ferritic stainless steel, and austenitic plus ferritic duplex stainless steel. 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, low carbon stainless steel plate, high molybdenum stainless steel plate, high purity stainless steel plate, etc. According to the performance
