摘要
通过分析不同热处理工艺对NM360耐磨钢的组织和力学性能的影响,研究了NM360耐磨钢最佳回火温度。结果表明:NM360耐磨钢在250℃回火时硬度大、强度高,且伸长率及冲击韧性较好,耐磨性优良,符合NM360耐磨钢使用要求。
Through analyzing the effects of different heat treatment processes on the microstructure and mechanical properties of NM360 wear-resistant steel,the optimum tempering temperature of NM360 wear-resistant steel was studied.The results showed that:when tempered at 250℃,NM360 wear-resistant steel had high hardness,high strength,good elongation and impact toughness,and excellent wear resistance,which met the requirements of NM360 wear-resistant steel.
