Stainless Steel Duplex 2205 is the most widely used duplex (ferritic/austenitic) stainless steel grade. It finds applications due to both excellent corrosion resistance and high strength. Duplex 2205 is a nitrogen enhanced stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels.Duplex Steel 2205 is not generally suitable for use at temperatures above 300°C as it suffers from precipitation of brittle micro-constituents, nor below -50°C because of its ductile-to-brittle-transition.
