It contains more than 18% chromium, as well as about 8% nickel and a small amount of elements such as molybdenum, titanium, and nitrogen. Good comprehensive performance and resistance to corrosion in various media. The commonly used grades of austenitic stainless steel include 1Cr18Ni9, 0Cr19Ni9, etc. The Wc of 0Cr19Ni9 steel is less than 0.08%, marked as "0" in the steel grade. This type of steel contains a large amount of Ni and Cr, resulting in the steel being in an austenitic state at room temperature. This type of steel has good plasticity, toughness, weldability, corrosion resistance, and non magnetic or weak magnetic properties. It has good corrosion resistance in oxidizing and reducing media, and is used to make corrosion resistant containers and equipment linings, transportation pipelines, resistant equipment parts, etc. In addition, it can also be used as the main material for stainless steel watch accessories. Austenitic stainless steel generally adopts solid solution treatment, that is, heating the steel to 1050~1150 ºC, and then water cooling or air cooling to obtain single-phase austenite structure
