General Description
Inconel X-750 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, pressure vessels, tooling, and aircraft structures.

Inconel X-750 is available as wire, strip, sheet, rod and bar. In the wire form, this grade is covered by specification AMS 5698 for No. 1 Temper and AMS 5699 for spring temper grade. No. 1 Temper has a higher service temperature than Spring temper, but lower tensile strength.
