Disclosed is structural low-alloy manganese cast steel having increased hardness and wear resistance, and an article made therefrom. In particular, after carrying out conventional bulk hardening followed by tempering, the disclosed steel has hardness of approximately 418 to 512 HB and is suitable for use in railway engineering, in particular for manufacturing parts of freight car trucks such as a friction wedge. Due to improved hardness and wear resistance of the parts made of the steel according to the present invention, an increase in inter-repair service life, in particular, of the friction wedge/friction plate friction pair is provided without a significant increase in cost for the parts.
