A new concept of creating steels to provide high resistance to wear and damageability to the rolling surface of wheels was proposed, requirements for a set of mechanical characteristics of such steels were developed and chemical composition of steel for a new generation of railway wheels, as well as heat treatment mode during their repair surfacing was substantiated. 15 Ref., 2 Tabl., 4 Fig.
Keywords: high-strength railway wheels, slider, notch, wear, operational reliability
