摘要
针对传统的高锰钢作为履带板材料在实际应用中的不足,试验采用了一种新型的铸造低合金高强度耐磨钢替代。试验结果表明,该钢经过合理的合金设计和适当的处理工艺,可获得高强度、较高的硬度和韧性、良好的综合性能;同时由于合金中加入了镍,改善了钢的低温脆性,有利于高寒地区的冬季作业。
A kind of new low-alloy steel with strength was studied to overcome the deficiency of traditional high-manganese steel used in making creeper truck.Combined reasonably selected composition with proper heat-treatment process,this kind of steel possesses high strendth,hardness and toughness.Its synthetical property is very well.Moreover,because of the Nickel addition,its low-temperature fragility is improved.Therefore,creeper truck made of this material is more suitable to working in low-temperature areas than those made of other materials.
