2205 Duplex Stainless Steel Pipe
Product Description
2205 Duplex stainless steel alloy is a duplex stainless steel composed of 22% chromium,3% molybdenum and 4.5% nickel nitrogen alloy. It is featured by high strength, good impact toughness and good overall and local resistance to stress corrosion.

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..
