... together ( figs. 4 and 6 ) as is often observed in the molybdenum free austenitic chromium steels, the SCC cracks tend to run out from the pits. This can be explained by increased chloride concentration in the pit compared to that of the external electrolytes 5 . Fig. 6 shows stress corrosion cracks...
