Inconel X-750 is a nickel-chromium alloy which has been made precipitation-hardenable by the increments of aluminum and titanium. Inconel X-750 has great resistance to erosion and oxidation along high tensile and creep break properties at temperature up to 1300ºf (700ºc). Because of X-750's great unwinding safety it is helpful for applications as high-temperature springs and fasteners, X-750 is likewise utilized as a part of gas turbines, rocket engines, atomic reactors, weight vessels, tooling and airplane structure.

Rod, Bars and Forgings are available with the following heat treatments
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.
With a heat treatment of 1800°F anneal + 1400°F/1hr, FC to 1150°F, hold at 1150°F for total precipitation-treating time of 6 hr, AC (solution treatment plus short furnace-cool precipitation treatment). This treatment of short furnace cool aging achieves only slightly lower properties than does AMS 5670 and AMS 5671.
Rods and Bars X-750 is available from 1/2" diameter to 6" diameter in 1/4" increments. From 6" diameter to 10" diameter it is available in 1/2" increments.
