René 41 is a nickel-based high temperature alloy developed by General Electric. It retains high strength in the 1200/1800°F (649/982°C) temperature range. Nickel-based high temperature alloy René 41 is used in jet engine and missile components, and other applications that require high strength at extreme temperatures. René 41 is considered a Nickel alloy based upon its chemical composition.
René 41 Nickel alloy is an age hardening nickel base superalloy with exceptional strength from room temperature through about 1600°F. The René 41 alloy is sensitive to strain age cracking during welding. Sound welds can be made by the resistance and electron beam methods. GTAW using DC straight polarity requires good joint fit-up and cooling by means of copper backup bars or water-cooled fixtures. High Strength René 41 should be in the fully solution treated condition prior to welding. After welding the assembly should be solution treated using rapid heating and cooling rates through the 1200-1600°F range, followed by aging.
Nickel-based high temperature alloy René 41 has found applications in jet engine and high speed airframe components such as: afterburner parts, turbine casings, wheels, buckets, bolts, and fasteners.

Mechanical properties vary with the solution and aging treatments. Higher solution temperatures result in better room temperature ductility and elevated temperature creep-rupture strength. Lower solution temperatures give higher tensile strengths.
