Abstract
Testing for hydrogen-induced cracking (HIC) susceptibility of plate steels is now done routinely for process vessels exposed to wet sour service. A review is presented on the effect of various steelmaking practices on HIC testing behavior of the commonly employed SA516 carbon steel. In particular, variables such as sulfur content, casting (ingot versus continuous), and inclusion content are discussed. Commercial production results for the past several years are presented. Correlations amongst parameters are identified. Comment is given on the use of various calculation methods for specifying HIC test performance. The use of average measurements is recommended. Experiences with the testing of thick plates are reviewed.
