The invention belongs to the technical field of alloy materials, and particularly relates to wear-resistant manganese-boron steel, a track link section and a preparation method and application of the wear-resistant manganese-boron steel. On the basis of existing wear-resistant manganese-boron steel, under the condition that other expensive metal elements are not additionally added or the using amount of the metal elements is not remarkably increased, the hardenability of MnB series steel is improved by properly increasing the content of silicon in a system, optimizing the content of carbon and combining with limitation of elements such as Ni, Cu, Sn and Pb, and the wear resistance of the wear-resistant manganese-boron steel is improved. And the structure is refined, a uniformly dispersed hard phase is separated out, the mechanical property of the product is improved, and the wear resistance of the product is enhanced. Compared with the prior art in which other high-price alloy components are added (or added) and the use amount of relatively low-price silicon is increased, the material with high mechanical property and high through quenching is obtained, the production cost is greatly reduced, the fluctuation risk of product quality is reduced, and the material has high industrial utilization value.

    本发明属于合金材料技术领域,具体涉及一种耐磨锰硼钢、链轨节及其制备方法和应用。本发明在现有的耐磨锰硼钢的基础上,在不额外添加其他价格昂贵的金属元素或不显著增加这些金属元素用量的情况下,通过适量增加体系中硅的含量,并优化碳含量,以及结合Ni、Cu、Sn、Pb等元素的限定,来提高MnB系钢材的淬透性,细化组织并析出均匀弥散的硬质相,提高了产品的力学性能,增强了产品的耐磨性。相对于现有技术采用添加(或增加)其他的高价的合金成分,增加价格相对低廉硅的用量来获得高力学性能、高淬透的材料,大幅度地降低了生产成本,降低了产品质量的波动风险,具有高度的产业利用价值。
