Conclusions

After heat treatment consisting of heating in a protective atmosphere to (780–830)±20°C depending on the shot size, water-quenching, and medium-temperature tempering at 360±20°, the cyclic wear resistance of the steel shot increases from 30–50 cycles (in the as-cast condition) to 450–500 cycles. The shot microstructure changes from coarse martensite to a mixture of troostite and fine martensite.
