Project Description
Rene 41 (UNS N07041 / W.Nr. 2.4973)
Rene 41 (UNS N07041 / W.Nr. 2.4973) is an age hardening nickel base super alloy with has exceptional strength from room temperature through to between 650-980℃. Alloy 41 is designed for use in severely stressed high temperature applications. It is typically used in hot components for jet engines, rocket engines, turbine blades, turbine wheels, torque rings, bolting, springs and much more.
