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.
本发明公开了一种具有提高的硬度和耐磨性的结构低合金锰铸钢,以及由其制成的制品。具体地,在进行传统的整体淬火然后回火之后,所公开的钢具有大约418‑512HB的硬度,适用于铁路工程,特别是用于制造货车部件,例如摩擦楔块。由于由本发明的钢制成的部件的硬度和耐磨性得到改善,因此,提高了特别是摩擦楔块/摩擦板摩擦副的维护使用寿命,而部件的制造成本并没有显著增加。
