Inconel® X750 is a precipitation hardenable Nickel-Chromium alloy with high strength at temperatures up to 1300°F (704°C) and oxidation resistance up to 1800°F (982°C). Inconel® X750 offers excellent resistance to relaxation and as a result it is widely used for springs operating at elevated temperatures.
Suggested Operating Conditions: Optimum resistance to relaxation at temperatures up to 1000°F (538°C) with moderate or low stresses.
Suggested Operating Conditions: Optimum stress and low relaxation at temperatures up to 700°F (371°C)
Suggested Operating Conditions: Optimum resistance to relaxation at temperatures in the range 1000 – 1300°F (538 – 704°C).

Super alloys are also called high performance alloys. They contain a number of elements in a variety of combinations to reach the desired result. These alloys can function in environments with high temperatures and severe mechanical stress, and also in cases where high surface stability is needed. Super alloys have good creep and oxidation resistance.
Strengthening of super alloys is performed by work hardening, solid-solution hardening, and precipitation hardening methods.

INCONEL alloy X-750 (UNS N07750/W. Nr. 2.4669) 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.
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. In gas turbines, it is used for rotor blades and wheels, bolts, and other structural members. INCONEL alloy X-750 is used extensively in rocket-engine thrust chambers. Airframe applications include thrust reversers and hot-air ducting systems. Large pressure vessels are formed from INCONEL alloy X-750. Other applications are heat-treating fixtures, forming tools, extrusion dies, and test machine grips. For springs and fasteners, INCONEL alloy X-750 is used from sub-zero to 1200°F.
Depending on the application and the properties desired, various heat treatments are employed. For service above 1100°F, particularly where loads are to be sustained for long times, optimum properties are achieved by solution treating (2100°F) plus stabilisation treating (1550°F) plus precipitation treating (1300°F). For service below 1100°F, the alloy may be strengthened by precipitation treating after hot or cold working or by precipitation treating after equalising or solution treating. A furnace-cooling treatment is also used to develop optimum properties for some applications.
The various heat treatments and the properties developed are described under the section on Mechanical Properties.
Property values in this bulletin – the results of extensive testing – are typical of the alloy but, unless shown as limiting, should not be used as specification values.
