The stress corrosion cracking resistance of alloys SCF-19 and 15-15LC was compared in simulated drilling environments using low strain rate tests, NACE tensile tests and autoclave exposures of DCB and bent beam specimens. Alloy 15-15LC was extremely susceptible to stress corrosion cracking in chloride solutions both with and without H2S. Alloy SCF-19 showed no tendency to stress corrosion crack in any of the environments
tested.
