The fatigue test was carried out by simplified lifting method, and the fatigue characteristic curve of X12Cr13 stainless steel at stress ratio of R = 0.1 was plotted at a single point, with the result that the fatigue strength is about 0.5 times the tensile strength. The normal stress ratio R has significant effects on the fatigue life of X12Cr13 stainless steel. As the stress ratio R increases, the fatigue life of the material increases significantly. At the same stress ratio R, the type of fracture morphology of the fatigue specimens is not significantly influenced by the variation of the maximum load. Under the same maximum load condition, larger stress ratio R leads to finer and smoother fatigue fracture surface.
