Stainless steel plate is usually the general name of stainless steel plate and acid resistant steel plate. The development of stainless steel plate has laid an important material and technical foundation for the development of modern industry and scientific and technological progress. There are various stainless steel plates with different properties. They have gradually formed several categories in the process of development. According to the main chemical composition or some characteristic elements in the steel plate, it can be divided 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 and high-purity stainless steel plate. According to the performance characteristics and uses of the steel plate, it is divided into nitric acid resistant stainless steel plate, sulfuric acid resistant stainless steel plate, pitting resistant stainless steel plate, stress corrosion stainless steel plate, high-strength stainless steel plate, non-magnetic stainless steel plate, free cutting stainless steel plate and superplastic stainless steel plate.
