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, August 1985). This datasheet provides information on composition, physical properties, hardness, tensile properties, and bend strength as well as deformation and fatigue. It also includes information on high temperature performance as well as forming, machining, and joining. Filing Code: SS-661. Producer or source: Armco International Sales.
