What is Duplex Steel?

Duplex Steel suppliers is the most widely used duplex (ferritic/austenitic) stainless steel grade. It finds applications due to both excellent corrosion resistance and high strength. The standard duplex S31803 composition has over the years been refined by many steel suppliers, and the resulting restricted composition range was endorsed as UNS S32205 in 1996. DSS material gives better guaranteed corrosion resistance, but for much of the Duplex S31803 currently produced also complies with Duplex S32205, Duplex Stainless Steel Suppliers in India. 2205 is not generally suitable for use at temperatures above 300ºC as it suffers from precipitation of brittle micro constituents, nor below -50ºC because of its ductile-to-brittle-transition.
