General Information
Inconel Alloy® X-750 is a nickel-chromium austenitic alloy similar to Alloy 600 but made precipitation-hardenable by additions of aluminum and titanium. It has good resistance to corrosion and oxidation along with high tensile and creep-rupture properties at high temperatures to 1300°F (700°C). Extended applications that require high strength at temperatures beyond 1100°F (593°C) may require a solution treatment, with air cooling between intermediate and final aging.This material has excellent relaxation resistance and is non-magnetic. It has good elevated temperature strength properties to 1300ºF (700°C) and oxidation resistance to 1800ºF (983˚C). Inconel® X-750 is resistant to a wide variety of industrial corrosives under both oxidizing and reducing conditions. This alloy also has excellent resistance to chloride stress corrosion cracking in the fully age hardened condition.
