More than 18% chromium, it also contains about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good overall performance, corrosion resistant variety of media. Common austenitic stainless steel grades are 1Cr18Ni9,0Cr19Ni9 like. Wc 0Cr19Ni9 steel <0.08%, steel labeled “0.” This kind of steel contains large amounts of Ni and Cr, the steel at room temperature was austenitic state. Such steel has good ductility, toughness, weldability, corrosion resistance and non-magnetic or weakly magnetic, corrosion resistance are good in oxidizing and reducing medium, used to produce acid and equipment, such as corrosion resistant containers and equipment linings, pipelines, nitric acid resistant parts and other equipment, and also can be used as the main material of stainless steel jewelry watches.
Austenitic stainless steels commonly used solution treatment, is about steel heated to 1050 ~ 1150 ℃, and then air-cooled or water-cooled, in order to obtain a single phase austenite.
