INCONEL alloy 718SPF is an age-hardenable austenitic material whose strength is largely dependent on the precipitation of a gamma prime phase following heat treatment. The base alloy, however, possesses two-essential characteristics for super-plastic forming; grain size stability over time and temperature; and a combination of low flow stress and significant ductility. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, and tensile properties as well as creep and fatigue. It also includes information on low and high temperature performance. Filing Code: Ni-471. Producer or source: Inco Alloys International Inc.
