2205 Duplex Stainless Steel Plate Description
The yield strength of 2205 Duplex stainless steel is more than twice that of ordinary austenitic stainless steel, and it has enough plastic toughness required for molding. The wall thickness of storage tanks or pressure vessels made of duplex stainless steel is 30-50% less than that of commonly used austenite, which is conducive to reducing costs. 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 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..
