This age hardenable nickel base super alloy has very good strength
in temperatures up to about 980oC (1800oF).
It’s strength is generally comparable to that of Rene 41and
is generally superior to that of Alloy 718 at temperatures exceeding
650 - 705oC (1200 - 1300oF).
Applications include:
- Gas Turbine Engine Parts
- Aerospace Components
- Springs and Fasteners
