Alloy X-750 is a nickel-chromium alloy which has been made recipitation-hardenable by the additions of aluminum and titanium. This superalloy is used in applications that require oxidation and corrosion resistant qualities and high strength at high temperatures.
Due to X-750's excellent relaxation resistance it is useful for applications as high-temperature springs and bolts, X-750 is also used in gas turbines, rocket engines, nuclear reactors, pressure vessels, tooling and aircraft structures.
INCONEL alloy X-750 Mechanical Properties
INCONEL alloy X-750 may be given any one of a variety of heat treatments. Each develops special properties and puts the product form in the best condition for its intended application. In all conditions, alloy X-750 is resistant to oxidation up to 1800°F. The most often used heat treatments have been incorporated by the Society of Automotive Engineers in their AMS specifications* for various product forms.
