INCONEL Alloy X750 is a precipitation-hardenable nickel-chromium alloy used for its corrosion and oxidation resistance and high strength at temperatures to 1300°F. Although much of the effect of precipitation hardening is lost with increasing temperature over 1300°F, heat-treated material has useful strength up to 1800°F. Alloy X-750 also has excellent properties down to cryogenic temperatures.

Key Features

• Good creep rupture strength at high temperatures
• Not as strong as Nimonic 90
• Very good at cryogenic temperatures
• Age hardenable
• High temperature dynamic applications
