按照国标GB/T2975-2018的规定沿钢板的横向切取直径为8 mm的棒状拉伸比例试样，平行段标距为40 mm。按照国标GB/T 228.1-2010在ETM-105D型微机控制电子万能试验机上进行室温拉伸试验，应变速率为0.00025s-1。460MPa级抗震耐蚀耐火钢中板轧态的屈服强度波动统计结果为：461MPa~512MPa，属于正常波动。

According to the provisions of GB/T2975-2018, the rod tensile proportional sample with a diameter of 8 mm is cut horizontally along the steel plate, and the distance of parallel section is 40 mm. According to GB/T 228.1-2010, tensile test at room temperature was carried out on ETM-105D microcomputer controlled electronic universal testing machine with strain rate of 0.00025s-1. Statistical results of rolling yield strength fluctuation of 460MPa aseismic corrosion resistant refractory steel range from 461MPa to 512MPa, which is normal fluctuation.
