WebHowever, SOHIC susceptibility of “HIC Resistant” steels has not been restricted to the weldments. These steels have also demonstrated SOHIC susceptibility in the base metal [2, 3]. It has been shown that decreases in sulfur content, while decreasing susceptibility to HIC, may result in an increase in the susceptibility to SOHIC [4].
