Abstract

The 2.25Cr-1Mo steel is used for pressure vessel components and has sometimes suffered from hydrogen embrittlement. Therefore, it is important to investigate the effect of hydrogen on the embrittlement for 2.25Cr-1Mo steel. Under corrosion fatigue conditions, the effect of hydrogen embrittlement (HE) on corrosion fatigue crack growth rate (CFCGR) appears in different ways depending on the applied stress waveforms. This behavior has been clarified by previous theoretical and experimental analyses. In this paper, based on the cited theoretical analyses, the effect of stress wave form on CFCGR for 2.25Cr1Mo steel was investigated and the sensitivity to hydrogen embrittlement is examined for this material.
