Austenitic stainless steel refers to stainless steel with chromium and nickel as the main alloy elements and an austenitic structure at room temperature. When steel contains approximately 18% Cr, 8%~10% Ni, and approximately 0.1% C, it will have a stable austenite structure. Austenitic chromium-nickel stainless steel includes the famous 18Cr-8Ni steel and the high Cr-Ni series steel developed by increasing the Cr and Ni content and adding Mo, Cu, Si, Nb, Ti and other elements.
Austenitic stainless steel is non-magnetic and has good mechanical properties (high toughness and plasticity), which is easy to carry out machining, stamping and welding. The high chromium content greatly improves the corrosion resistance of the steel, because the surface is easy to form very dense and The strong chromium oxide protective film has good corrosion resistance and good heat resistance and low temperature performance in oxidizing environments. It is suitable for equipment and components with heavy loads and low corrosion resistance requirements, especially It has extremely wide range of uses in civil, light industry and other fields.
