Product Show

2205 Duplex stainless steel pipe has more than twice of yield strength than ordinary austenitic stainless steel, and it has enough plastic toughness required for molding. 2205 duplex stainless steel has excellent corrosion resistance. Because it contains 22% chromium and 3% molybdenum, it can show better corrosion resistance than 316L and 317L in most environments. This alloy also performs well when it comes to localized corrosion resistance. In oxidizing and acidic solutions, 2205 Duplex stainless steel pipe is highly resistant to pitting and crevice corrosion. Moreover, when compared with austenitic stainless steel with similar alloy content, its wear corrosion resistance and fatigue corrosion performance are better than austenitic stainless steel. Whether under dynamic load or static load conditions, 2205 duplex stainless steel has a higher energy absorption capacity than austenitic stainless steel, which has obvious advantages for structural parts to cope with emergencies such as collisions, explosions, etc.

Surface Treatment


Surface finish Characteristics & Application
NO.1 Hot-rolled surface, annealed and pickled, can be used as cold-rollingmaterial, industrial tanks and chemical devices.
NO.2D Cold-rolled, annealed and pick led with out skin passing the dullproducts can be used as auto mo bile parts, building materials andpiping.
NO.2B The surface brightness and flatness of NO.2B is better than NO.2D.Then through a special surface treatment to improve its chemicalproperties, NO.2B. could nearly satisfy comprehensive uses.
NO.3 Polished with abrasive belt of grit #100#120, have better brightness withdiscontinuous coarse stria, used as inner and external ornaments forbuilding, electrical appliances and kitchen utensils etc.
NO.4 Polished with abrasive belt of grit #150#180, have better brightness withdiscontinuous coarse stria, but thinner than NO.3. are used as bathtubbuilding inner and external ornaments electrical appliances, kitchenutensils and food processing equipment etc.
HL Polished with abrasive belt of grit #150-320 on the No.4.finish and hascontinuous streaks, mainly used as building ornaments, elevators, doorof building, frontal plate etc.
BA Cold-rolled, bright annealed and skin passed, the product has excellentbrightness and good reflexivity like mirror, used for electrical appliances,kitchen apparatus, ornament materials etc.
