    Abstract

    2.25Cr-1Mo steel is used as a pressure vessel component, which is 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 condition, the effect of hydrogen embrittlement (HE) on corrosion fatigue crack growth rate (CFCGR) appears in different manner depending on applied stress wave forms and it was clarified by previous theoretical and experimental analysis. In this paper, based on the theoretical analyses mentioned above, the effect of stress wave form on CFCGR for 2.25Cr-1Mo steel was investigated and the sensitivity of HE was discussed for this material.
