Nimonic 90 Strip 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.
Nimonic 90 is also known as Superimphy 90, Pyromet 90, and Udimet 90.
The chemical composition of Nimonic 90 is given in the following table.
| Element | Content (%) |
