Nimonic 90
Description:
Nimonic 90 (UNS N07090 / W.Nr. 2.4632) 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.
Features
Nimonic 90 has a high stress rupture strength and creep-resistant at temperatures to 920°C.
Applications
Nimonic 90 is typically used in extreme stress applications such as turbine blades, hot working tools, exhaust reheaters, disc and high-temperature springs.
