2205 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.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.

Duplex Stainless Steel Tubing has a chemical composition of approximately equal parts of austenite and ferrite which is why it has twice the design strength of normal austenitic and ferritic stainless steel tubing. Duplex stainless steel tubings have a wide range of corrosion resistance levels. They also have high resistance to stress corrosion cracking that they might have received from its ferritic side. Duplex stainless steels are still very much in their developing stages and there are constantly different brands being promoted, this should continue till an accomplished and proven grade emerges. Duplex stainless steel tubes are used by a number of companies across the globe because they are very cost effective.
