The chromium content is 18%, or so 8% nickel and elements of Molybdenum, Titanium, Nitrogen. Combination property is pretty well, can be corrosive for multiple mediums. Those steels possess excellent plasticity, toughness,weldability,corrosion resistance and Non-magnetism or weak magnetism, and good corrosion resistance in the medium of oxidability and reducibility, which are for processing the acid-resistant equipments, such as anti-corrosive vessel, equipment lining, running piping, equipment parts of nitric acid resistance, and also for main material of stainless steel horologe accessories. Austenitic stainless steel adopts solution treatment generally, that's to say, heating the steel to 1050~1150ºC, then water cooling or wind cooling, to obtain single phase austenite structure. Main steel grades are listed:
BS X2CrNil9-11, BS X8CrNiS18-9, BS X2CrNiMo17-12-2, BS X2CrNiMoN17-13-3, BS X1NiCrMoCu31-27-4.
