Altemp X-750 is a precipitation-hardenable nickel-base alloy that is highly resistant to chemical corrosion and oxidation and has excellent stress-rupture and creep properties at temperatures up to 815 deg C (1500 deg F) after suitable heat treatment. The alloy has oxidation resistance up to 980 deg C (1800 deg F). It is typically used in aircraft turbine and structural components. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, and joining. Filing Code: Ni-649. Producer or source: Allegheny Ludlum.
