Rene 41 Nickel base alloy steel

Rene 41 is a precipitation hardening, nickel-based high temperature alloy possessing high strength in the 1200/1800°F (649/982°C) temperature range. This alloy is designed for use in severely stressed high temperature applications.

Rene 41 Nickel alloy similar material is:UNS N07041

Rene 41 usually used in the following industries :
Rene 41 has found applications in jet engine and high speed airframe components such as: afterburner parts, turbine casings, wheels, buckets, bolts, and fasteners.

Corrosion Resistance
Rene 41 is highly corrosion and oxidation resistant. It provides very good resistance to jet engine combustion gases up to 1800°F (982°C).

Annealing
Lowest hardness is obtained by quenching from temperatures above the gamma prime solvus temperature - 1950°F (1066°C) is usually satisfactory. Hardness will be in the Rockwell B 98/C 30 range, depending on the rapidity of the quench. It is unlikely that large sections can be quenched rapidly enough to obtain low hardness.

Hot Working/Forging
Rene 41 is best forged between an initial furnace temperature of 2100°F (1149°C) and an optical finishing temperature of 1850/1900°F (1010/1038°C).

Cold Working
Rene 41 work hardens rapidly; frequent anneals will be required. Aging after cold working can be result in strain age cracking.Cold worked sections must be heated rapidly through the aging temperature range, 1200/1700°F (649/927°C), to the solution or annealing temperature ot prevent strain age cracking. A sizable amount of cold reduction between anneals is mandatory. Small reductions, such as sizing passes, must be avoided.

Welding
Rene 41 can be welded by inert gas-arc methods. The part should be in the solution treated condition, 1950/1975°F (1066/1080°C) for 4 hours, and preferably water quenched.
