ABSTRACT:
A wheel has both wear resistance and heat-crack resistance sufficient for use in a high-speed railway vehicle. The chemical composition of a base steel comprises 0.4 to 0.75 % C, 0.4 to 0.95% Si, 0.6 to 1.2% Mn and less than 0.2% Cr. The wheel has a pearlitic microstructure in a region of at least 50 mm in depth from the tread surface of the wheel. When the tread of the wheel is quenched, a particular cooling process is applied in order to obtain the pearlitic structure.
