The crack growth rates of A537 c1.1 steel and its weld metal have been investigated both in air and in artificial sea water.The effects of stress ratio,frequency,residual stress of welds as well as corrosion products on cor- rosion fatigue crack growth rate have been exa- mined.Some electrochemical reactions occurred during tests and models for describing the cor- rosion fatigue crack growth process in low strength of offshore structural steel were discussed.
