What we are:

Several decades of years for stainless steel products, our staff are specialists and sophisticated. Give you more professional service with our excellent products.

 

General Properties:

Austenitic stainless steel has stable austenitic structure in normal temperature, it possesses very high corrosion resistance, good cold workability and good toughness plastic, weldability and non-magnetic. It has been widely used in chemical, oil refining, boiler, food and other industries of the heat exchanger condenser, evaporator and fluid transportation ,etc.

Compared to common austenitic stainless steel, super austenitic stainless steel has higher cleanliness uniformity, mechanical properties, more fine structure; 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 be satisfied by ordinary austenitic stainless steel: Petroleum chemical industry of butyl acetate acid, terephthalic acid,polyvinyl chloride, and other media environment; Inorganic chemical industry of sulfuric  acid, ferric sulfate, soda, phosphate and other media environment; The crude oil refining of crude oil desalting, reduced pressure distillation environment; The ultra supercritical boiler, superheater, reheater, final reheater, etc.
