Rene 41 is an age hardenable nickel base alloy that has very
high strength at elevated temperatures, particularly within
the range of 650 - 980oC (1200 - 1800oF).
Required mechanical properties can be tailored by selection
of various combinations of cold work and/or heat treatments.
Rene 41 also has good oxidation resistance.
Applications include:
- After Burner Parts
- Turbine Castings
- Bolts
- Other fasteners
