Inconel X-750 (Alloy X-750), with UNS N07750 and W.Nr. 2.4669, is a nickel-chromium alloy known for its excellent strength, oxidation, and corrosion resistance at high temperatures. It is widely used in gas turbines, jet engines, and other high-stress environments where superior performance is required at elevated temperatures.
Inconel X-750 offers excellent resistance to thermal-fatigue and creep, along with outstanding stability at high temperatures. This makes it a preferred material for applications in the aerospace, power generation, and chemical industries, particularly for components like turbine blades, combustion chambers, and heat exchangers that are exposed to extreme conditions.
