What is Inconel 750 material?
Nickel Alloy X-750 / Inconel X-750®
Technical Data Sheet
Alloy X-750 is a nickel-chromium alloy that has been made precipitation hardenable by the addition of aluminum and titanium. Alloy X-750 has good corrosion and oxidation resistance and high tensile and creep-rupture properties at temperatures up to 1300ºF (700ºC). X-750 is used as high temperature springs and bolts due to its excellent resistance to relaxation, and is also used in gas turbines, rocket engines, nuclear reactors, pressure vessels, tools, and aircraft structures.
