摘　　要：针对大型生产线低合金结构Q345BH型钢强度偏低的状况,对大型线H型钢的性能从取样位置和钢材时效进行了系统性分析,并制定了相应的措施和对策,从而改善了Q345B大型H型钢的性能。In view of that the strength of low alloy structural steel Q345B H-Beam in large production line was on the low side,the performance of H-Beam in large production line was systematically analyzed from the aspects of sampling positions and the aging behavior of the steel,and the corresponding measures and countermeasures were formulated,thus the performance.of Q345B large H-Beam was improved.

关 键 词：Q345B H型钢 屈服强度
