Inconel X-750 is a precipitation-hardenable nickel-chromium superalloy with aluminum and titanium additions, used primarily in aerospace gas turbine engines, fasteners, and high-temperature structural applications requiring strength retention to approximately 1300°F (700°C). The annealed condition provides a softened baseline microstructure suitable for machining and forming prior to age hardening, with moderate strength and good ductility as supplied per AMS 5542.
