| Application | INCOLOY alloy 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 chorides. Because of the alloy’s 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. |
