Nimonic alloy 90 is a precipitation hardenable nickel-chromium-cobalt alloy strengthened by the addition of Titanium and Aluminium. Alloy 90 has a high stress rupture strength and creep-resistant at temperatures to 920°C. Nimonic Alloy 90 is typically used in extreme stress applications such as turbine blades, hot working tools, exhaust reheaters, disc and high-temperature springs.
The recommended heat treatments for Nimonic 90 are as follows:
Solution Treatment - 1080
°C (1975
°F) for 8 hours + air cool or oil/ water quench
Precipitation Heat Treatment (As per BS HR2) - 700
°C (1290
°F) for 16 hours + air cool
