Inconel® Alloy X-750, Haynes® X-750, or Nickel Alloy 750 is a precipitation hardenable nickel-chromium super-alloy. This super-alloy is typically found in applications that require oxidation and corrosion resistant qualities and high strength at high temperatures. Much of the effect of precipitation hardening is lost with temperatures over 1300°F; heat-treated material has useful strength up to 1800°F. Nickel alloy 750 also has excellent properties in cryogenic temperatures.
