Austenitic stainless steel tubes have a stable austenite group at room temperature. The steel contains about 18% Cr, Ni is more than 8%, C is about 0.1%, has high corrosion resistance, good cold workability and good toughness , plasticity, welding and non-magnetic. Widely used in
Industrial heat exchangers, non-magnetic condensers, evaporators, and fluid transport applications in industries such as engineering, oil refining, boilers, and foodstuffs.
Super austenitic stainless steel tubes have higher cleanliness, uniformity, mechanical properties than ordinary austenitic stainless steel tubes, finer texture, better surface quality, better resistance to harsh media localized corrosion and better Process manufacturing properties, etc.
It is used in industrial environments where working conditions are harsher, corrosion is stronger, and common austenitic stainless steels cannot meet, such as: Dibutyl Acetate, Acetic Acid, Formic Acid, Terephthalic Acid, Polyvinyl Chloride and other medium environments in the petrochemical industry Inorganic chemical sulphuric acid
Acidic ferric sulfate, soda ash, phosphoric acid and other media environments; Crude oil desalination in crude oil refining, vacuum distillation environment; supercritical boiler superheater, reheater, no class reheater and so on.
