摘　　要：安钢结合当前高强建筑结构用钢的市场,紧随用户需求,研发出Q420GJC高强建筑用钢板。采用低碳+高锰配加铌+钒+铝复合微合金化的成分体系,制定两阶段轧制工艺,轧后钢板获得铁素体+珠光体的组织结构和各位置均匀的力学性能。钢板各项性能数据稳定,满足建筑结构用钢的标准和客户使用要求。Q420GJC high strength steel plate is developed in Anyang Steel based on the current high strength construction steel market and user＇ needs. The microstructure of the ferrite and pearlite and the mechanical properties are obtained by using composite micro alloying components system of low-C ＋ high-Mn ＋ Nb ＋ V ＋ Al and two stage rolling process.The performance of the steel plate is stable and can meet the standards and customers＇ requirement for the building structure steel.
