General properties
Alloy X-750 / Inconel X-750 ® (W-Nr. 2.4669; UNS N07750)
A nickel-chromium alloy similar to Alloy 600 but made precipitation hardenable by additions of aluminium and titanium. It has good resistance to corrosion and oxidation along with high tensile and creep-rupture properties at temperatures to 1300°F (700°C). Its excellent relaxation resistance is useful for high-temperature springs and bolts.
Used in gas turbines, rocket engines, nuclear reactors, pressure vessels, tooling, and aircraft structures.
