该数据集主要对首钢生产的460MPa级抗震耐蚀耐火钢20-28mm中板进行轧态的屈服强度波动分析,取样自首钢4300mm宽厚板产线工业生产的钢板,采用全板厚拉伸试样进行试验和结果统计,统计结果为:461MPa~512MPa,性能稳定性优良,满足项目的屈服强度波动要求。
This data set mainly analyzes the fluctuation of yield strength of rolled 20-28mm medium plate of 460MPa seismic and corrosion resistant refractory steel produced by Shougang. Samples are taken from industrial steel plates produced by shougang 4300mm wide and thick plate production line. Full-thickness tensile samples are used for testing and statistical results. 461MPa~512MPa, excellent performance and stability, meet the yield strength fluctuation requirements of the project.
