Austenitic stainless steel is a stainless steel material with good corrosion resistance and mechanical properties. It gets its name from the crystal structure of austenite, in which iron atoms form a solid solution with alloying elements such as chromium and nickel. Austenitic stainless steels usually contain higher chromium and nickel contents to enhance their corrosion resistance. Due to its good performance and wide application fields, austenitic stainless steel is widely used in the chemical industry, petroleum, aerospace, medical equipment, food processing and other industries. At the same time, with the development of science and technology, the types and properties of austenitic stainless steel have been continuously improved and innovated to meet the needs of different fields
