Abstract Hydrogen embrittlement susceptibility of 40CrNi3MoV steels with Si contents of 0.25% and 1.16% and the strength level of 1500 MPa was investigated by means of slow strain rate tests. The reduction of notch tensile strength after introduction of hydrogen was used to characterize hydrogen embrittlement susceptibility and compact specimens were used to investigate hydrogen-induced crack propagation. Results show that the higher Si content 40CrNi3MoV steel was less susceptible to hydrogen embrittlement than the lower Si content 40CrNi3MoV steel with the same strength level of 1500 MPa, resulting from more and finer carbides which may act as hydrogen trapping sites and prevent hydrogen from diffusing to fracture process zone.
