Rough classification of stainless steel

Date:2018/7/28 10:59:04
The development of stainless steel has laid an important material and technological foundation for the development of modern industry and the progress of science and technology. Stainless steel has many varieties and different properties. It has gradually formed several major categories in the development process. It is divided into four major categories, martensitic stainless steel (including precipitation hardening stainless steel), ferrite stainless steel, austenite stainless steel and austenite and ferritic duplex stainless steel, and classified according to the main chemical composition in steel or some characteristic elements in steel, which are divided into chromium stainless steel, chrome nickel stainless steel and chromium nickel molybdenum. Rust steel and low carbon stainless steel, high molybdenum stainless steel, high purity stainless steel and so on. According to the properties and uses of steel, it is classified into nitric acid stainless steel, sulphuric acid resistant stainless steel, pitting stainless steel, stress corrosion resistant stainless steel, high strength stainless steel and so on. According to the functional characteristics of steel, it is divided into low temperature stainless steel, magnetic stainless steel, magnetic stainless steel, magnetic stainless steel, magnetic stainless steel, magnetic free stainless steel, magnetic free stainless steel, magnetic stainless steel, magnetic stainless steel, Easy cutting stainless steel, superplastic stainless steel and so on. At present, the commonly used classification methods are classified according to the characteristics of microstructure and chemical composition of steel and the combination of the two methods. Martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, double phase stainless steel and precipitation hardening stainless steel, etc. are divided into two major categories: chromium stainless steel and nickel stainless steel.
