About Alloy 718 API

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