摘　　要：分析了影响45Mn17Al3钢磁导率性能的主要因素。通过工业试验确定了合理的化学成分、热处理工艺制度及试样表面加工要求等。试验结果表明,45Mn17Al3钢在800、4 000及8 000 A/m三个磁场强度下,相对磁导率μr≤1.005,满足了某些特殊工程对磁性能的较高要求。The main influence factors of magnetic permeability of 45Mn17Al3 steel have been analyzed. Reasonable chemical composition, heat treatment process and sample surface processing requirements have been confirmed through industrial experiment. The results show that the relative magnetic permeability of 45Mn17Al3 steel is not more than 1.005 in magnetic field intensity of 800, 4 000 and 8 000A/m, which can satisfy some special engineering requirement that demands higher magnetic performance.
