Incoloy Alloy 945 is a nickel-base precipitation-strengthened alloy that provides 860 MPa (125 ksi) minimum yield strength and an excellent combination of ductility and impact strength. The nickel content is sufficient to provide protection against chloride-ion stress-corrosion cracking. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ni-666. Producer or source: Special Metals Corporation.
