ASTM B637 UNS N07750 super alloy inconel X750 pipe tube
Inconel Alloy X-750, inconel x750 Tube is a nickel-chromium austenitic alloy similar to Alloy 600 but made precipitation-hardenable by additions of aluminum and titanium. Inconel X750 alloy refers to the precipitation-hardening nickel alloy bar or forging manufactured to ASTM B637 UNS N07750. It should be either hot worked or cold worked and is primarily used for high-temperature service.
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.
