Inconel X-750 - ASTM B693
Inconel X-750 is a high temperature nickel alloy that is highly resistant to chemical corrosion and oxidation. It has high stress-rupture strength and low creep rates under high stresses at temperatures up to 1500°F. Alloy X-750 is the most common type of Inconel and is an excellent choice when designing a flat spring for extreme temperature environments.
Nominal Chemical and Physical Properties of Inconel X750:
Minimum Tensile Strength psi x 103 150
E - Modulus of Elasticity psi x 106 31
Maximum Operating Temperature 750-1100°F

Alloy X-750 is a nickel-chromium alloy which has been made precipitation-hardenable by the additions of aluminum and titanium. Alloy X-750 has good resistance to corrosion and oxidation along with high tensile and creep rupture properties at temperature up to 1300ºF (700ºC). Due to X-750's excellent relaxation resistance it is useful for applications as high-temperature springs and bolts, X-750 is also used in gas turbines, rocket engines, nuclear reactors, pressure vessels, tooling and aircraft structures.
