摘要	Low-cycle fatigue behaviors of 316LN stainless steel with three surface roughness were investigated in high-temperature pressurized water at different strain rates (0.001-0.04%/s) under strain amplitude of 0.3%. More significant reduction of fatigue life was found for samples with higher roughness. The environmental fa-tigue effects with different surface roughness were strain rate dependent and the weakened effect at low strain rates was related to the plastic deformation layers which enhanced the diffusion of Cr and played an inhibiting role on fatigue crack growth. Besides, the fatigue damage mechanisms for polished and rough samples are discussed.
