DEVELOPMENT OF CORROSION-RESISTANT ALLOYS FOR THE OIL AND GAS-INDUSTRY

The introduction of corrosion resistant alloys (CRAs) into the oil and gas industry began in the early 1970s. The history of this developmen t is reviewed, including economic incentives, manufacturing challenges , new alloy developments, and identification of risks of stress corros ion cracking upon exposure to produced brines. Both the advances in co rrosion engineering required to defining acceptable CRA/environment ap plications and associated advances in corrosion science are highlighte d, as well as the trends in future developments.
