N2 - In this paper, the tensile fatigue tests using small compact specimen were conducted by the corrosion and hydrogen embrittlement fatigue testing method which authors have proposed. Based on these results, the quantitative separated estimations of the sensitivity of Corrosion, Hydrogen Embrittlement(HE) and Facet-like Fracture Hydrogen Induced Dislocation Pile-up (F-HIDP) were made by using the acceleration factor, D∗, that is the ratio of fatigue crack growth rate to that under atmospheric condition.
