WebMay 6, 2024 · Hydrogen-induced cracking (HIC), a type of wet hydrogen sulfide (H2S) damage, is a condition commonly observed in the oil refining, petrochemical, chemical, and gas sectors. If a certain level of hydrogen sulfide is detected in carbon steel, low-alloy, or other high-strength steels, it's deemed a sour service environment. WebHydrogen Induced Cracking (HIC) occurs when carbon steel is exposed to hydrogen sulphide (H2S) and is the direct result of electrochemical corrosion reactions between the sour service or wet H2S environment. Particularly common to the Oil and Gas Industry where the use of steel pressure vessels is widespread, the risks of this should be ...
