Request Information
Inconel X-750 is a nickel-chromium alloy similar to INCONEL alloy 600 but made precipitation hardenable by additions of aluminum and titanium. Inconel X-750 has good resistance to corrosion and oxidation along with high tensile and creep-rupture properties at temperatures to about 1300°F (700°C). Its excellent relaxation resistance is useful for high-temperature springs and bolts. Inconel X-750 is used in gas turbines, rocket engines, nuclear reactors, pressure vessels, tooling and aircraft structures. Standard product forms are round, flats, extruded section, forging stock, plate, sheet, strip, pipe, tube and wire.
