摘要	The corrosion fatigue behavior of 316LN SS hollow specimen was investigated in high-temperature pressurized water at different dissolved oxygen (DO) concentrations (<5-200 ppb). The fatigue life of 316LN SS significantly increased with increasing DO concentration from < 5-20 ppb, while the effect of DO on fatigue lives apparently saturated at above 20 ppb (20-200 ppb). DO plays a significant role in microstructurally small cracks rather than mechanically small cracks. The oxidation characteristic of slip bands affects the crack initiation process. The effect of DO on the fatigue crack initiation mechanism is discussed.
