Special Metals INCONEL® 706 Precipitation Hardening Alloy, Forged Disc, Solution Treated

Subcategory: Superalloy; Iron Base; Nickel Base

Material Notes:
Iron content in composition table calculated as remainder. Ni content includes Co. Nb content include Ta.

Tensile strength (ultimate and yield), reduction of area, and elongation values reported here are typical for Forged Disc, Solution Treated samples. Density and magnetic permeability are typical of annealed INCONEL® alloy 706. Other property values are typical of INCONEL® alloy 706.

For optimum creeep 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.

For tensile-limited applications, the alloy receives a two part heat treatment as follows: Solution treat 1700-1850°F (925-1010°C) for a time commensurate with section size, then air cool. Precipitation treatment 1350°F (730°C)/8 hr, furnace cool at 100°F (55°C)/hr to 1150°F (620°C)/8 hr, air cool.
