Hydrogen Effect on Fatigue Strength of Structural Steels
In this paper hydrogen effect on fatigue strength of structural steels is mainly reviewed on the basis of the author's experimental results. The emphasis is focused upon the hydrogen related corrosion fatigue crack propagation behavior of the ship structural steels and their welded joints in sour crude oil environment. It can be concluded that the environment enhancement of the fatigue crack propagation rate in sour crude oil is dependent of hydrogen evolved by reaction of H2S and H2O in the sour crude oil with structural steels.
