Hydrogen-induced cracking (HIC) and sulfide stress cracking (SSC) of both acicular ferrite and ultrafine ferrite in H2S environments were evaluated. The results show that the two microstructures have the optimum HIC resistance as well as the good mechanical properties. Moreover, acicular ferrite has the better SSC resistance than ultrafine ferrite. [Copyright &y& Elsevier]
