Inconel Alloy X750, ATI X750, Haynes X750

UNS N07750

INCONEL® Alloy X-750 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. Alloy X-750 also has excellent properties down to cryogenic temperatures.

INCONEL® Alloy X-750 applications include gas turbines, rotor blades, wheels, bolts and other structural components. INCONEL® Alloy X-750 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 INCONEL® Alloy X-750. Other applications are heat-treating fixtures, forming tools, extrusion dies and test machine grips. For springs and fasteners, INCONEL® Alloy X-750 is used from sub-zero to 1200°F.
