摘要

The method of medium-carbon 60S2А steel preliminary treatment with electrolytic hydrogen to increase its fragmentation under static explosion is considered. The Pf parameter, which determines the number of steel fragments weighing 4–5 g or more per weight unit of the material, is proposed for evaluating the steel fragmentation. When the hydrogen concentration in steel changes in the range of 0.07–4.36 ppm, the Pf parameter value increases by 25%. Comparison of the proposed method with the 60S2A steel preliminary quenching method showed an increase in the Pf parameter value by 56%, indicating its perspective for use.
