The development of stainless steel has a long history. With the continuous improvement of science and technology, the variety and performance of stainless steel have also been continuously improved and improved. At present, stainless steel has become one of the important materials and has played an important role in various fields.
Stainless steel can be divided into Austenite stainless steel, iron stainless steel, martensite stainless steel and precipitated hardening stainless steel according to the tissue structure. In practical applications, the choice of stainless steel is mainly determined according to the use environment and use. For example, Austeine stainless steel is widely used in food, medical, chemical industry and other fields due to its good corrosion resistance and comprehensive performance; matoral stainless steel is often used in the fields of tools and bearings because of high strength and hardness.
