Forging conditions
Forging is made at a range of temperature included between 1150 and 950°C, then cooled at appropriate conditions for the final thermal treatment and obtain required characteristics. In any case, please contact us.
Properties / Main use conditions
Precipitation hardening treatment alloy, near alloy 75, but with better values to creeping, to be used until 815°C.
Main applications
Gas turbine components, blades and rings, flame tubes, heat treatment oven components. Exhaust valves for internal combustion engines.
Heat treatment
Solution : 1040°C during 1 hour, then air cool.
Ageing :
- 699°C / 16 hours / Air, or
- 849°C / 24 hours + 699°C / 16 hours / Air
