Product Description

2205 Duplex Stainless Steel Bar Description

2205 Duplex stainless steel bars have more than twice of yield strength than ordinary austenitic stainless steel, and it has enough plastic toughness for molding. Moreover, it has good local corrosion resistance, and 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 bars have a higher energy absorption capacity than austenitic stainless steel, which is why they have obvious advantages for structural parts to cope with emergencies such as collisions, explosions, etc..
