Abstract HPM X-750 is a precipitation-hardenable nickel-chromium alloy that is well suited for a wide range of corrosive and oxidizing environments where strength must be maintained to elevated temperatures. The alloy composition provides a product that performs well at elevated temperatures up to 700 deg C (1300 deg F). The strength can be increased by heat treatment. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on high temperature performance as well as forming, heat treating, and joining. Filing Code: Ni-638. Producer or source: Hamilton Precision Metals.
