Rene 62 Precipitation‑Hardening Wrought Nickel‑Base Superalloy
is a vacuum‑melted precipitation‑hardening wrought nickel‑base superalloy. It possesses desirable high‑temperature oxidation resistance and excellent weldability. The alloy features a relatively slow age‑hardening response together with superior high‑temperature ductility, making it well‑suited for high‑stress welded assemblies, hot working dies and other demanding high‑temperature service parts.
Rene 62 achieves maximum service temperature up to 813 ∼C, and maintains superior tensile & yield strength compared to Inconel 718 and Rene 41 for applications operating below 730 ∼C.
