Hastelloy X750 is a precipitation-hardenable nickel-chromium alloy used for its corrosion and oxidation resistance and high strength at temperatures to 1300°F. Although much of the effect of precipitation hardening is lost with increasing temperature over 1300°F, heat-treated material has useful strength up to 1800°F. Hastelloy X750 also has excellent properties down to cryogenic temperatures.
Hastelloy X750 applications include gas turbines, rotor blades, wheels, bolts and other structural components. Hastelloy X750 is also used in rocket-engine thrust chambers. Airframe applications such as thrust reversers and hot-air duct systems. Pressure vessel applications are formed from Hastelloy X750. Other applications are heat-treating fixtures, forming tools, extrusion dies and test machine grips. For springs and fasteners, Hastelloy X750 is used from sub-zero to 1200°F.
