Nickel Chorme Alloy Inconel X-750 625 600 601 800 718 (UNS N07750, Alloy X750, W. Nr. 2.4669, NiCr15Fe7TiAl)
Inconel X-750 (UNS N07750, Alloy X750, W. Nr. 2.4669, NiCr15Fe7TiAl)
General Description
Inconel X750 is a nickel-chromium alloy similar to Inconel 600 but made precipitation-hardenable by additions of aluminum 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.
