Series of screening tests were run in tilting autoclaves to evaluate performance of selected, potential inhibitors in preventing chloride stress corrosion attack of Type 347 austenitic stainless steel in alkaline-phosphate boiler water containing 50 or 500 ppm chloride. From the test results, several inhibitors were tested further to evaluate concentration effects. Nitrate appeared to be a satisfactory inhibitor for boiler applications. Sodium sulfite also effectively prevented chloride corrosion cracking by scavenging oxygen. 5.8.4
