Springs operating from cryogenic temperatures up to 1300°F (704°C), fasteners and components requiring resistance to high temperature and corrosive environments.


Inconel® 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® X750 offers excellent resistance to relaxation and as a result it is widely used for springs operating at elevated temperatures.
