Properties of high manganese austenitic cast steel are not satisfactory; therefore, this material should be
hardened. Currently, the commonly used method of hardening does not allow eliminating problems related to
premature wear of railway frogs. Therefore, many studies have been carried out to find an alternative method
to obtain improved wear resistance of such elements. The article presents an analysis of the mechanical and
tribological properties of base and hardened, by different methods, high-manganese cast steel applied for
turnouts. Tests were performed for three hardening methods: explosive, pressure-rolling, and dynamic impact.
The results were compared with the properties of base material after saturation treatment. The conducted
tests allowed the determination of hardness profiles of hardened surfaces, as well as the wear resistance and
coefficient of friction, and the obtained results are very promising. Hardening by dynamic impact provided
much better results in relation to presently used explosive hardening technology.
