Datasheet: Rene 41

Rene 41

Rene 41 is an age hardenable nickel base alloy that has very high strength at elevated temperatures, particularly within the range of 650 – 980 °C (1200 – 1800 °F).

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.

Available in all profile options
