Inconel® Alloy X-750 is a nickel-chromium alloy similar in basis to Inconel® 600, but modified with the addition of aluminum and titanium to be suitable for precipitation hardening through heat treatment. This gives the alloy high tensile strength, excellent oxidation and corrosion resistance, and exceptional relaxation resistance at high temperatures up to approximately 700°C.
These properties make X-750 particularly valuable for applications requiring long-term mechanical stress and temperature stability.
Inconel® X-750 stands out due to its combination of mechanical strength, creep resistance, and oxidation resistance, even under prolonged thermal stress. The alloy is enhanced through precipitation hardening, with aluminum and titanium contributing to a robust and stable microstructure.
Its excellent relaxation resistance makes the material particularly suitable for spring elements and fasteners that must reliably perform at high temperatures. Additionally, X-750 offers good corrosion resistance in oxidative and mildly reducing environments, extending its lifespan under intensive use.
The alloy is well-suited for machining and welding, although heat treatment and careful process control are required for optimal performance.
Inconel® Alloy X-750 is widely used in applications where high temperatures, prolonged mechanical stress, and oxidation resistance converge. Examples of applications include:
Gas turbine components
Rocket engine parts
Nuclear reactor components
Pressure vessels and high-pressure systems
Tooling for high-temperature processes
Aircraft components and high-temperature springs and fasteners
Thanks to its combination of mechanical performance and thermal stability, Inconel® X-750 is a preferred material for the aerospace, power generation, and space industries.
Inconel® Alloy X-750 is the solution for applications demanding extreme thermal and mechanical performance under prolonged stress.
