Alloy X-750 is a nickel-chromium alloy which has been made precipitation-hardenable by the additions of aluminum and titanium. Alloy X-750 has good resistance to corrosion and oxidation along with high tensile and creep rupture properties at temperature up to 1300ºF (700ºC). Due to X-750's excellent relaxation resistance it is useful for applications as high-temperature springs and bolts, X-750 is also used in gas turbines, rocket engines, nuclear reactors, pressure vessels, tooling and aircraft structures.
AMS 5667 - 1625°F/24hr, AC + 1300°F/20 hr, AC (Equalising plus precipitation treatment). AMS 5667 Rod, Bars and Forgings have high strength and notch rupture ductility up to 1100°F
AMS 5668 - 2100°F anneal + 1550°F/24 hr, AC, +1300°F/20hr, AC (triple heat treatment). AMS 5668 has maximum creep, relaxation and rupture strength above about 1100°F.
AMS 5670 - 1800°F anneal + 1350°F/8hr, FC to 1150°F. Hold at 1150°F for total precipitation-treating time 18 hr, AC (solution treatment plus furnace cool precipitation treatment). Due to the heat treatments AMS 5670, AMS 5671 and AMS 5747 have increased tensile properties and reduced heat treatment time service up to about 1100°F.
AMS 5542 - 1300°F/20hr, AC (Constant-temperature precipitation treatment). AMS 5542 has high strength up to 1300°F
AMS 5598 - 1350°F/8hr, FC to 1150°F, hold at 1150°F for total precipitation-treating time of 18hr, AC (furnace-cool precipitation treatment. AMS 5598 has high strength up to 1300°F (Increased tensile properties to about 1100°F).
With heat treatment 1400°F/1hr, FC to 1150°F hold at 1150°F for total time of 6hr, AC.
