Special Metals INCONEL® 706 Precipitation Hardening Alloy, Forged Disc, 3 Part Heat Treatment
Categories:	Metal; Nonferrous Metal; Nickel Alloy; Superalloy; Iron Base
Material Notes:	Tensile strength (ultimate and yield), reduction of area, and elongation values reported here are typical for Forged Disc, 3 Part Heat Treatment samples. Density and magnetic permeability are typical of precipitation hardened INCONEL® alloy 706. Other property values are typical of INCONEL® alloy 706. For optimum creep and rupture properties, the alloy receives a three part heat treatment as follows: Solution treat 1700-1850°F (925-1010°C) for a time commensurate with section size, then air cool. Stabilizing treatment 1550°F (845°C)/3 hr, air cool. Precipitation treatment 1325°F (720°C)/8 hr, furnace cool at 100°F (55°C)/hr to 1150°F (620°C)/8 hr, air cool. Data provided by the manufacturer, Special Metals.
