Abstract During dynamically charging four kinds of C90 tubular steels with hydrogen,the concentration of divisible hydrogen c0 is directly proportional to cathodic current i, and thenormalized threshold stress σc.(H)/σt decreases linearly with hi c0, i.e., σc(H)/σt=A-B ln c0.The concentrations of diffusible hydrogen in the steels during immersing in the H2S saturationsolution, c0*, have been measured. The values of σc(H)/σt during dynamically charging withic corresponding to c0* for the four steels are consistent with the threshold stress σc(H2S)/ctduring SCC in H2S solution. The result shows that the threshold stress during charging with asuitable current density ic can substitute for the threshold stress during SCC in H2S solution.
