General 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. Nimonic 90 has a high stress rupture strength and creep-resistant at temperatures to about 920°C. Nimonic 90 is better suited for extremely high temperatures than Inconel X 750 (or Inconel 718).
