View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.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.
