Technical Data Sheet
Alloy R41 (Rene 41) is an age hardening nickel base super alloy with has exceptional strength from room temperature through to between 650°C – 980°C (1200 – 1800ºF). R 41 is designed for use in severely stressed high temperature applications. R41 (Rene 41) is typically used in hot components for jet engines, rocket engines, turbine blades, turbine wheels, torque rings, bolting, springs and much more.
