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.Nitronic 19D is an alloy with a mixed ferrite and austenite microstructure. The alloy provides a good compromise of strength, formability, and economy with slightly less corrosion resistance than the reference duplex alloy 2205 (see Alloy Digest SS-462 and 501).
