Rene 41 Nickel Alloy Sheet
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). Rene 41 nickel alloy sheet is designed for use in severely stressed high temperature applications. Typically used in hot components for jet engines, rocket engines, turbine blades, turbine wheels, torque rings, bolting, springs and much more.
Rene 41 nickel alloy sheet also has good oxidation resistance. Required mechanical properties can be tailored by selection of various combinations of cold work and/or heat treatments.
