Special Metals INCOLOY® Alloy 945 Nickel-Iron-Chromium Alloy, Pump Shaft Grade, Cold Worked and Aged Rod (UNS N09945)
Categories:	Metal; Nonferrous Metal; Nickel Alloy
Material Notes:	INCOLOY® alloy 945 (UNS N09945) is a high-strength, corrosion-resistant alloy designed for demanding applications in the oil and gas industry. The properties of this age hardenable nickel-iron-chromium alloy are enhanced by its contents of molybdenum, copper, niobium, titanium, and aluminum. The nickel content results in resistance to chloride-induced stress corrosion cracking. Nickel, in conjunction with the molybdenum and copper, gives alloy 945 outstanding resistance to general corrosion in reducing media. Molybdenum imparts resistance to localized attack (pitting and crevice corrosion). The chromium provides resistance in oxidizing environments. Niobium, titanium and aluminum participate in the age hardening reaction that occurs during heat treatment. Their interaction forms gamma prime and gamma double prime precipitates, which strengthen the alloy. INCOLOY 945 is suitable for downhole oil and gas applications requiring high strength and corrosion resistance in aggressive sour wells containing high levels of hydrogen sulfide and chlorides. Because of the resistance to stress cracking in environments rich in hydrogen sulfide, it is suitable for downhole and surface gas-well components including tubular products, valves, hangers, landing nipples, tool joints and packers. The alloy can also be used for fasteners, pump shafting and high strength piping systems. Data provided by the manufacturer, Special Metals.
