Inconel X750 (also known as UNS N07750) is a nickel-chromium alloy blended with aluminum and titanium to make it precipitation hardenable. It is resistant to corrosion and oxidation and has good mechanical properties at high temperatures up to 700°C (1290°F), including high tensile and creep-rupture strengths.
Inconel X750 physical characteristics:
Hardness: HRC 32 – 42 in solution and precipitation heat treated condition (depending on heat treatment).
Density: 0.299 pounds per cubic inch.
Modulus of Elasticity: 31 MSI in STA conditions.
Coefficient of Expansion: 7.8 x10-6 in/in/F, RT-800F. 8.4 x10-6 in/in/F, RT-1200F.
Inconel X750 chemical composition:
| C | Mn | Si | S | Cu | Fe | Ni | Cr |
| 0.08 max | 0.35 max | 0.50 max | 0.001max | 0.50 max | 5.0-9.0 | 70.00-75 | 14.00 – 17.00 |
Inconel X750 Processing Characteristics:
Inconel X750 has a machinability rating of 16. Like other nickel-based superalloys, Inconel X-750 is not as machinable as most steels, including stainless steels. However, with the correct choice of tool material, speed, feed and coolant, it can be machined in the annealed or age-hardened condition. Due to the strength and hardness of Inco X750, any rough machining should be done prior to precipitation hardening.
