Nickel Alloy Inconel 625 is a nickel-based heat-resistant alloy. It is characterized by having high tensile, creep, and rupture strength. Conventionally cast or wrought components in this type of nickel alloy have typically excellent fatigue and thermal- fatigue properties combined with oxidation resistance. IN625 is expected to have good corrosion resistance in various corrosive environments.

Stress Relief (SR):
Stress relieve at 2100°F +/- 25°F for 2 hours +/- 15 minutes in vacuum. Follow by argon gas cool with cooling rate equivalent to air cool or faster.
Heat Treatment (HT):
Solution heat treat at 2150°F +/- 25°F for 1 hour +/- 10 minutes. Follow by 6 bar argon gas quench.
