Comparative studies of precipitation-hardening corrosion-resistant nickel-base alloys used in the oil and gas industry are conducted. Corrosion-electrochemical properties of ÉP718 and Inconel 718 alloys are studied, and composition and microstructure are analyzed. It is observed that the passivity of these alloys may be affected significantly by the amount and composition of nonmetallic inclusions. It is demonstrated that these alloys may be used as analogs.
