Precipitation Hardenable Nickel-Base Superalloy

ATI X-750™ alloy (UNS N07750) is a precipitation hardenable nickel-base superalloy which is used in applications requiring high strength to approximately 1300°F (704°C) and oxidation resistance to approximately 1800°F (982°C). Following heat treatment, ATI X-750™ alloy possesses high stress-rupture strength and a low creep rate at temperatures up to approximately 1500°F (816°C). ATI X-750™ alloy is also highly resistant to corrosion. This alloy has been used primarily in the aerospace industry for items such as gas turbine rotor blades, gas turbine wheels, bolts, and other gas turbine structural parts. It has also found use in jet engine afterburners and airframe and missile structures. Non-aerospace applications include heat treat fixtures, forming tools, and extrusion dies.
