Abstract

The mechanical properties of 38Х2Н2МА steel components after electric-discharge machining (EDM) are experimentally studied. The strength of workpieces obtained by turning and EDM is compared. The life of samples in few-cycle fatigue is determined. The life of 38Х2Н2МА steel samples after EDM is 30% less than after turning. There is little difference in the strength of 38Х2Н2МА steel samples after EDM and after turning.
