The microstructure after hydrogen attack and the propagation path of fatigue crack have been observed by optical microscopy. The results showed that hydrogen attack resulted in an obvious increase in fatigue crack growth rate for 20G steel;however, the threshold △K value decreased at the beginning of hydrogen attack, and increased at the successive stage for the same material.The 2.25Cr-1Mo steel showed a lower susceptibility to hydrogen attack due to the action of element Cr and Mo, not resulting in a significant change in fatigue crack behaviour.It is suggested that the increase in the threshold △K value could be attributed to the crack closure effect caused by the tortuous cracking path.
