SCC susceptibility of three kinds of steel in synthetic seawater was evaluated by slow strain rate tests (SSRT) as a function of solution pH, electrochemical potential and strain rate. Strain rate dependance on SCC susceptibility was remarkable in the corrosion environment in terms of ultimate tensile strength, reduction of area and rupture elongation. Strain rate effects were examined in detail in terms of applied strain rate and local strain rate as well. Local strain rate at necked region after Pmax was much higher than averaged nominal rate at 4.17×10-7 sec-1 and several cracks were observed only at the necked region in the S.S.W.
