WebMay 19, 2009 · What is Hydrogen Induced Cracking (HIC)? Hydrogen Induced Cracking (HIC) occurs when carbon steel is exposed to hydrogen sulphide (H 2 S) and is the direct result of electrochemical corrosion reactions between the sour service or wet H 2 S environment. Hydrogen Induced Cracking (HIC) in the Oil and Gas Industry . Particularly common to the … 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].
