摘　　要：针对建筑用HRB400E高速线材性能不合格问题进行了化学成分、力学性能、金相组织的试验分析,结果表明,Mn元素含量过多,将产生回火索氏体和粒状贝氏体异常组织,从而影响钢材的力学性能。In order to solve the unqualified performance of HRB400E high speed wire for construction,analysis of chemical composition,mechanical properties and metallographic structure are carried out.The results show that excessive Mn will produce abnormal microstructures,i.e.tempered sorbite and granular bainite,which will affect the mechanical properties of steel.

关 键 词：HRB400E高速线材 显微组织 性能不合格
