CarTech 617 (Pyromet 617) is a corrosion and oxidation-resistant, high-temperature nickel-chromium-cobalt-molybdenum alloy. It is solid-solution strengthened with cobalt and molybdenum. Oxidation resistance is imparted through the addition of chromium and aluminum. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ni-777. Producer or source: Carpenter Technology Corporation.
