Heat Treatment

Inconel 706 requires a specific three-stage heat treatment to achieve its optimal mechanical properties [7†L19-L20]:

Step	Temperature	Time	Cooling	Purpose
Solution Treatment	1800°F (982°C)	—	Rapid cooling	Dissolve precipitates; soften for forming
Stabilization	1550°F (843°C)	3 hours	Air cool	Form η phase for creep ductility
Precipitation Hardening	1325°F (718°C)	8 hours	Furnace cool to 1150°F (621°C), hold 8 hours, air cool	Develop γ' and γ'' strengthening phases

Fabrication Guidelines:

Annealing: 1700–1850°F (925–1010°C) + rapid cooling
Forging: 1800–2100°F (980–1150°C) with controlled cooling
Hot Working: 1600–2100°F (872–1149°C)
Solution Treatment: 1800°F (982°C) per AMS 5701

Applications

With balanced high-temperature strength, superior processability and stable fatigue resistance, AMS 5701 UNS N09706 alloy bars are core materials for high-end power and aerospace equipment:

Aerospace Gas Turbine Components: Turbine discs, engine casings, rotating shafts and structural fasteners for aero engines
Land-Based Industrial Gas Turbines: High-temperature load-bearing parts, power turbine components and precision fastening assemblies
Energy & Power Equipment: High-temperature and pressure-resistant structural parts for power generation equipment
High-Precision Industrial Components: Custom high-strength, heat-resistant mechanical parts requiring complex forming and welding

AMS 5701 UNS N09706 (Inconel 706) nickel superalloy bar is a cost-effective high-temperature structural material. With high precipitation hardening strength, better fabricability than 718 alloy, and excellent heat and corrosion resistance, it has become the preferred material for aerospace and industrial gas turbine core components.
