Nickel X-750 is a nickel-chromium alloy that has been strengthened with the additions of titanium and aluminum to improve its characteristics. This precipitation-hardenable alloy is a popular option for many industries because it has a number of advantages for high-temperature and high-stress applications.
Nickel X-750 is a fantastic choice for usage in tough settings because of its excellent corrosion and oxidation resistance. Additionally, even at temperatures as high as 1300°F (700°C), this alloy has exceptional tensile and creep rupture capabilities.
In aircraft structures, X-750 is used to make components such as high-temperature springs, bolts, and pressure vessels. The alloy’s ability to maintain its properties even at high temperatures ensures that these components are able to withstand the extreme temperatures and loads encountered during flight.
NICKEL X-750 Round Bar diameters range from 0.125″ to 14.00″ diameter.
Heat-treated strength: Although much of the effect of precipitation hardening is lost with increasing temperature over 1300°F, heat-treated Nickel X-750 still maintains useful strength up to 1800°F. Additionally, this alloy has exceptional properties even at low cryogenic temperatures, making it a versatile option for a range of applications.
Various heat treatments: To achieve the desired properties for a particular application, various heat treatments can be employed. For use above 1100°F, where loads are to be sustained for long periods of time, optimum properties are achieved through solution treating (2100°F), stabilize treating (1550°F), and precipitation treating (1300°F). For use below 1100°F, the alloy can be strengthened through precipitation treating after hot or cold working, or after equalizing or solution treating. A furnace-cooling treatment can also be used to develop optimum properties for certain applications.
Excellent relaxation resistance: Due to its excellent relaxation resistance, X-750 is a great choice for high-temperature springs and bolts. This alloy is also used in gas turbines, rocket engines, nuclear reactors, pressure vessels, tooling, and aircraft structures.
In conclusion, ALLOY X-750 is a versatile and high-performance alloy that offers a range of benefits for use in high-temperature and high-stress applications. Its good resistance to corrosion and oxidation, combined with its ability to maintain high tensile and creep rupture properties at various temperatures, make it a popular choice for a variety of industries.
