The stress corrosion behavior of fine graincd, low alloy steels has been investigated using constant strain rate tensile tests. Studied materials were a A508 Class II type KS05 (German grade: 22 NiMoCr 3 7) and a A533 B Class I (German grade: 20 MnMoNi 5 5). The susceptibility to stress corrosion cracking was determined as a function of the amount of dissolved oxygen and temperature using cylindrical smooth specimen (DIN 50125) in purified water ...
