Sulfide stress cracking (SSC) is a type of environmental cracking that occurs in metals, particularly in high-strength steel alloys, when they are exposed to a sulfide-containing environment under tensile stress. This phenomenon is of particular concern in industries such as oil and gas, petrochemicals, and other applications involving sour environments, where hydrogen sulfide (H₂S) is present.
