摘要

Sulfide stress cracking (SSC) has been the subject of investigation since the late 1940's, when a mysterious form of brittle failure began to be observed in steel equipment used to produce oil and gas containing hydrogen sulfide. While the role of hydrogen sulfide in promoting increased levels of hydrogen in steels was recognized early on, researchers disagreed on the mechanism responsible for SSC. Initial theories that SSC was a form of stress corrosion cracking eventually gave way to the current understanding that the phenomenon is caused by hydrogen embrittlement. Research into the effects of hardness, microstructure, chemical composition, and other factors in determining the susceptibility of steels to SSC led to the establishment of industry standards for SSC-resistant materials.
