| Abstract: | Fatigue limit is of importance to drill steel 55 SiMnMo since it is being widely used in China. Specimens were heat-treated in three different ways to investigate their fatigue limits through tension, impact and bending tests under corrodible conditions. A prediction equation is thus derived from S-N diagram to estimate the fatigue limit. Results show that an optimum fatigue limit can be expected if using a drill bar made from 55 SiMnMo steel through proper normalizing plus tempering. |
