Specific features of fragmentation of hydrogen-charged 60S2A steel during static explosion tests

To increase the fragmentation of medium-carbon 60С2А steel in the conditions of a static explosion, a method of its preliminary treatment with electrolytic hydrogen is proposed. The Pf parameter is proposed for evaluating the steel fragmentation, which determines the number of steel fragments weighing 4–5 g or more per weight unit of the material. It was found that when the hydrogen concentration in steel changes in the range of 0.07–4.36 ppm, the value of the Pf parameter increases by 25%. Comparison of the proposed method with the method of preliminary quenching of 60C2A steel showed an increase in the value of the Pf parameter by 56%, which indicates its perspective use.
