Duplex alloy 2205 is a nitrogen-enhanced, ferritic-austenitic stainless steel. It has high resistance to stress-corrosion cracking (SCC); pitting; crevice and general corrosion. It has roughly twice the yield strength of austenitic stainless grades and it has good weldability. Some uses include heat exchangers, downhole instrument tubing, and applications in desalination plants. All Gibson Tube Duplex 2205 products meet the tighter composition limits of UNS S32205 to enhance corrosion resistance. This datasheet provides information on composition, physical properties, elasticity, tensile properties, and bend strength. It also includes information on corrosion resistance as well as heat treating and machining. Filing Code: SS-813. Producer or source: Gibson Tube.
