In addition, a fatigue design curve for carbon and low alloy steels (metal temperatures not exceeding 370 °C) is shown in Fig. 4 for a load ratio, R, of −1. The diagram was obtained from Total Materia [4] and The French code RCCM [5].It was further considered that, due to the ball mill's corrosive environment, no fatigue limit applies beyond 1x10 6 cycles (nonfilled squares in Fig. 4).
