The invention discloses urban rail wheel steel and an urban rail wheel prepared by using the urban rail wheel steel. The urban rail wheel steel comprises the following chemical components of, in percentage by mass, 0.55%-0.65% of C, 0.17% -0. 37% of Si, 0.60%-0. 80% of Mn, less than or equal to 0.035% of P, less than or equal to 0.035% of S, 0.10%-0.25% of Cr, less than or equal to 0.25% of Ni, less than or equal to 0.25% of Cu, 0.01%-0.15% of V, and the balance Fe and inevitable impurity elements. According to the urban rail wheel steel and the urban rail wheel prepared by using the urban rail wheel steel, under the condition that plastic toughness indexes of the wheel are maintained, the hardness of the section 30mm below the tread of the wheel is improved by 5%, the wear resistance is improved by 30% or more, the strength, hardness and wear resistance of a wheel rim can be greatly improved, and the anti-stripping performance, the scratch resistance and the anti-contact fatigue performance of the wheel are improved.
本发明公开了一种城轨车轮用钢及使用该城轨车轮用钢制备的城轨车轮,该城轨车轮用钢包括按质量百分比计的如下化学成分:C:0.55%~0.65%、Si:0.17%~0.37%、Mn:0.60%~0.80%、P:≤0.035%、S:≤0.035%、Cr:0.10%~0.25%、Ni:≤0.25%、Cu:≤0.25%、V:0.01%~0.15%,其余为Fe和不可避免的杂质元素。本发明的城轨车轮用钢及使用该城轨车轮用钢制备的城轨车轮,在保持车轮塑韧性指标相当的情况下,车轮踏面下30㎜处断面硬度提高5%,耐磨性提高30%以上,能够大幅提高车轮轮辋的强度、硬度和耐磨性性能,改善车轮的抗剥离性能、抗擦伤性能和抗接触疲劳性能。
