Duplex 2205 is a two-phase, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless steel,2205 is the most widely used duplex (ferritic/austenitic) stainless steel grade. Duplex S32205 gives better guaranteed corrosion resistance, but for much of the Duplex S31803 currently produced also complies with Duplex S32205. 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.

Due to its high chromium, molybdenum, and nitrogen content, Duplex 2205 demonstrates superior corrosion resistant properties to 316 and 316L in most environments.Duplex S32205 stainless steel is widely used in Chemical processing, transport and storage,Oil and Gas exploration and processing equipment,Marine and other high chloride environments,Pulp and paper digesters, liquor tanks and paper machines.
