A new concept of creating steels to provide high resistance of the rolling surface of wheels to wear and damage was
proposed, requirements for a set of mechanical characteristics of such steels were developed and chemical composition
of steel of a new generation for railroad wheels, as well as heat treatment mode during their repair surfacing were substantiated.
