Inconel® X-750, also known as Nickel Alloy X-750, is popular and
cost-effective precipitation-hardenable nickel-chromium alloy.
Inconel X-750s wide spread use is due to its numerous benefits
which include:
- High strength at temperatures to 1500°F (816°C) after suitable heat
treatment
- Creep-rupture strength at high temperatures to about 700oC (1290oF)
- High tensile and creep-rupture properties
- Resistance to a wide variety of industrial corrosives under both
oxidizing and reducing conditions
- Excellent workability including machinability and welding
- Resistance to chloride ion stress-corrosion cracking
- Precipitation hardenable

Inconel X750 Additional Information:
Physical Properties
Hardness: HRC 32 – 42 in the solution and precipitation heat treated
condition (depending on heat treatment).
Density: 0.299 lbs per cubic inch.
Modulus of Elasticity: 31 MSI in STA condition.
Coefficient of Expansion: 7.8 x10-6 in/in/F, RT-800F. 8.4 x10-6 in/in/F, RT-1200F.
Machining
Inco X750 has a Machinability rating of 16. Like other nickel-base
superalloys, the machinability of Inconel X-750 is inferior to that
of most steels including stainless steels. Nevertheless, with
proper selection of tool materials, speeds, feeds, and coolants, it
can be machined in either the annealed or age-hardened condition.
Due to the strength and hardness of Inco X750, one should perform
any rough machining before precipitation hardening.
Welding
Inconel X750 has fair welding ability, particularly in conjunction
with gas-tungsten-arc (GTA), plasma-arc, and electron-beam welding.
Inconel 718 weld filler is the preferred choice to help resist strain age
cracking. Welding is generally carried out on solution annealed
material and appropriate post-weld heat treatment is employed to
develop the desired properties. The precipitation hardened alloy is
also weldable, but weld joints are susceptible to cracking and will
be relatively soft and weak until heat treated. A full post-weld
solution, anneal and precipitation heat treatment is most often
applied to obtain optimum properties in weldments.
Forming
Forming for Inconel X-750 is fair to good in the solution annealed
condition. Due to its rapid strain hardening rate, frequent
in-process anneals are necessary when complex shapes are desired.
Corrosion Resistance
Inco X750 has good resistance to general corrosion and stress
corrosion over a wide range of temperatures under both oxidizing
and reducing conditions.
