INCONEL® Alloy X750 Coil, Strip, Foil, to AMS 5542 and AMS 5598
Springs operating from cryogenic temperatures up to 1300°F (704°C), fasteners and components requiring resistance to high temperature and corrosive environments.
INCONEL® Alloy X750 is a precipitation-hardenable Nickel-Chromium alloy with high strength at temperatures up to 1300°F (704°C) and oxidation resistance up to 1800°F (982°C). INCONEL® Alloy X750 offers excellent resistance to relaxation and as a result it is widely used for springs operating at elevated temperatures.
