Description
Inconel 718API
Alloy 718API is widely used in the oil and gas industry. Where wells have high concentrations of hydrogen sulphide, carbon dioxide and chlorides athigh pressures and temperatures, Alloy 718API is the alloy of choice. This alloy demonstrates high resistance to chloride and sulphide stress corrosioncracking in addition to high strength and good corrosion resistance.
