摘要：

An experimental investigation has been carried out on the fatigue crack growth behavior of CSA G40. 21M 350 WT steels in air and in seawater. Effects of temperature, load ratio, frequency and waveform on fatigue crack growth rates have been studied. A basic relationship between the material coefficients, C and m, has been obtained.
