ZYTC Alloy X -750 (UNS N07750) Precipitation-Hardenable Nickel Alloy
When applications demand exceptional creep resistance and retained strength under sustained load up to 700°C, material selection is critical. As an ISO 9001 and AS9120 certified supplier, ZYTC Alloy presents this technical guide for Inconel X-750.
I. Product Information
Material Name: Inconel X-750 (UNS N07750 / W.Nr. 2.4669)
Definition: Precipitation-hardenable nickel-chromium alloy with exceptional creep and rupture resistance up to 700°C (1300°F) via gamma prime (γ') strengthening.
Core Value: Superior relaxation resistance under sustained load at elevated temperatures.
Aerospace: Turbine blades, rings, rocket engine parts
Nuclear: Core springs, fasteners (PWR/BWR)
Industrial: High-temp springs, bolts, pressure vessels
Selection Boundaries:
Need higher strength? → Choose Inconel 718
Need corrosion resistance? → Choose Inconel 625
Need oxidation >700°C? → Choose Inconel 601
Cost-sensitive? → Choose A-286

Fabrication Guidelines:
Welding: Challenging (strain-age cracking risk). Use annealed material + matching filler. Post-weld solution + age required.
Hot Work: 1040-1205°C. Avoid below 980°C.
Machining: Very difficult. Rough machine annealed, finish after aging (0.07% shrinkage).
