JIS G3459 Stainless steel tube, stainless steel industrial piping
Austenitic stainless steel pipe has stable austenite structure at normal temperature, the steel contains about 18% of Cr, more than 8% Ni, about 0.1% C, it possesses very high corrosion resistance, good cold workability and good toughness, plastic, welding and non-magnetic. It has been widely used in chemical, refining, boiler, food and other industries heat exchanger, non-magnetic condenser, evaporator, liquid transportation industry, etc.
Compared to common austenitic stainless steel ,super austenitic stainless steel has a higher cleanliness uniformity, mechanical properties, more fine organization, better surface quality, more excellent resistance to harsh medium local corrosion resistance and better process manufacturing performance, etc., It can be used in harsher working condition, stronger corrosive industrial environment, which can not be satisfied by ordinary austenitic stainless steel : petroleum chemical industry of butyl acetate acetic acid, terephthalic acid ,polyvinyl chloride (PVC)and other media environment; The crude oil refining of crude oil desalting ,reduced pressure distillation environment ,the ultra supercritical boiler , superheater , rehearter, final reherater,etc
