A review on the effect of microstructure on hydrogen induced cracking behaviour in pipeline and pressure vessel steels

Abstract

Recently, the demand for energy is increasingly higher, and to meet the demand, more pipeline and pressure vessels are used to transport and store energy. Steels served in such environment need to have basic mechanical property, as well as excellent hydrogen induced cracking performance. Because hydrogen induced cracking failure will not only cause huge economic losses, but also have a harmful impact on the environment, it is necessary to study the impact of hydrogen induced cracking on steel and how hydrogen induced cracking occurs and expands. In this paper, the most important factor affecting hydrogen induced cracking, microstructure, was introduced.
