INCONEL® X750 2.4669 – UNS N07750 – NiCr15Fe7TiAl

Inconel® X-750 is a precipitation-hardenable nickel-chromium alloy used for its corrosion and oxidation resistance and high strength at temperatures to 1300ºF (704ºC). Although much of the effect of precipitation hardening is lost with increasing temperature over 1300ºF, heat-treated material has useful strength up to 1800ºF (980ºC). Alloy X-750 also has excellent properties down to cryogenic temperatures. The economics of Inconel® alloy X-750 coupled with its availability in all standard mill forms has resulted in applications in a wide variety of industrial fields.

Applications

  • Gas turbines
  • Rotor blades, wheels, bolts and other structural members
  • Airframe applications
  • Large pressure vessels
  • Heat-treating fixtures, forming tools, extrusion dies…

General characteristics

Depending on the application and the properties desired, various heat treatments are employed. For service above 1100ºF (593ºC),
particularly where loads are to be sustained for long times, optimum properties are achieved by solution treating (2100ºF-1150ºC) plus
stabilization treating (1550ºF-843ºC) plus precipitation treating (1300ºF-704ºC).
