摘　　要：采用自然时效和堆垛时效两种方式,通过不同的时效方式比较HRB400热轧带肋钢筋的屈服强度、抗拉强度和伸长率的变化,为质量检测和控制提供理论依据,可预测热轧带肋钢筋HRB400的使用安全性,并用以指导销售和用户异议处理。The yield strength,tensile strength and elongation of HRB400 hot- rolled reinforced bar were compared by putting it in natural aging and stacking aging. The result may provide theoretical foundation for quality test and control,predict the application safety of HRB400 hot-rolled reinforced bar and guide sales and users objection handling.
