摘要/Abstract

摘要： 研发了满足磨煤机复杂服役工况的高强度耐磨钢HNM450。其抗拉强度1727 MPa，断后伸长率14.5%，平均HBW硬度值522，-20 ℃冲击功38 J，具有良好的强度、塑性和低温韧性。模拟磨煤机实际服役工况的腐蚀磨损对比试验结果显示：HNM450产品200 ℃高温pH=5的弱酸性潮湿环境和200 ℃高温，pH=9的弱碱性潮湿环境下的耐腐蚀耐磨性能均明显优于HARDOX450钢。HNM450钢已经用于下游用户磨煤机的制造，实现了对进口耐磨钢HARDOX450的国产化替代。

Abstract: The high-strength wear-resisting steel HNM450 to meet the complex working conditions of the coal mill has been developed. Its tensile strength is 1727 MPa,elongation after fracture is 14.5%,average HBW hardness number is 522,and impact energy at -20℃ is 38J,it has good strength,plasticity and low temperature toughness.The comparative test results of corrosion and wear simulating the actual working condition of the coal mill show that the corrosion and wear resistance of HNM450 products at 200 ℃ high temperature,pH=5 in the weak acidic humid environment and at 200 ℃ high temperature,pH=9 in the weak alkaline humid environment is obviously better than that of HARDOX450 steel. HNM450 steel has been used in the manufacture of coal mills for downstream users,realized the domestic substitution of imported HARDOX450 steel.
