Test Study on Fatigue Property for Forging and Casting Steels of Grade E

Abstract:

The forging steel of grade E and casting steel of grade E are usually applied to making train coupler. The fatigue property tests have been carried out for the forging steel of grade E and the casting steel of grade E by using the up and down method and grouping method in the paper. The two kinds of steels fatigue limits have been obtained with the up and down method. With the grouping method, the P-S-N curve equations of high-cycle fatigue have been obtained. The confidence level is 90% and the probabilities of failure are 10%, 20%, 30% and 40%. The test results show that the fatigue property of the forging material are superior to the casting apparently . To some extent, the test results are valuable for fatigue reliability designating of train coupler.
