Finishing Options

Rene 41 Nickel Sheet

Excellent high-temperature strength.


Rene 41 is a precipitation-hardenable nickel-chromium alloy with additions of titanium and aluminium.

Rene 41 is a nickel sheet product for severely stressed high-temperature applications.


Rene 41 is a precipitation-hardenable nickel-chromium alloy with additions of titanium and aluminium to promote increased strength. The nickel-based high-temperature alloy maintains high strength at temperatures ranging from 649 to 982°C (1200 to 1800°F). The alloy finds use in severely stressed high-temperature applications while promoting high corrosion and oxidation resistance. Applications include rocket engines, turbine blades, combustion chambers, and afterburners. The mechanical properties of the alloy may be adjusted by cold working or utilising different heat treatments. Overall strength is achieved by various solution annealing and ageing heat treatments.


Other Names

Rene 41 sheet is marketed under various names,including Haynes® R-41 and Udimet Alloy® R41.
