摘　　要：NM360低合金高强度耐磨钢具有高硬度和耐磨性,适用各种工况下的大型钢结构件,可以满足多种耐磨工况。结果表明,NM360耐磨钢具有良好的焊接性能,与普通碳素钢焊接后焊接接头力学性能优良;同时可以通过合理的焊接工艺控制焊接变形。The low-alloy high-strength wear-resisting steel with high hardness and good wear resistance is applied for large steel structure under different circumstances. The results show that NM360 has good welding performance. The welded joint has good mechanical properties after welding with common carbon steel. At the same time, the welding deformation can be controlled by reasonable welding process.
