Abstract Stress corrosion cracking (SCC) of 316 L stainless steels manufactured with different procedures were investigated in simulated BWR environment. The effects of grain boundary network on SCC are discussed. Twin boundaries show stronger resistance to SCC than other types of boundaries. Grain size has significant influence on SCC though residual strain has more effect. Smaller grains result in more SCC initiation sites, while larger grains result in that the crack propagates locally deeper due to less restrictions from less triple points in the grain boundary network. Theoretical calculation is implemented to estimate the grain size effect on crack propagation.
