What is Inconel X-750?
Alloy X750 / INCONEL X750
Alloy X750 / Inconel X750 is a precipitation-hardened nickel-chromium alloy that offers corrosion and oxidation resistance and high strength to 1300°F. Although most of the effects of precipitation hardening disappear as temperatures exceed 1300°F, heat-treated material retains useful strength up to 1800°F. Alloy X-750 also exhibits excellent properties at cryogenic temperatures.
