该数据集主要对首钢生产的28mm规格460MPa级抗震耐蚀耐火钢中板进行轧态低温冲击性能检测,将试样在冲击试验机上进行低温冲击试验,结果显示-40℃低温冲击性能为307J,319J,274J,冲击功均值达到300J,低温韧性良好,达到目标的冲击韧性要求。
The data set is mainly used to test the low temperature impact performance of the medium plate of 460MPa seismic and corrosion resistant steel produced by Shougang under rolling condition. The samples are tested on the impact testing machine at low temperature. The results show that the low temperature impact energy at -40℃ is 307J, 319J, 274J, and the average impact energy is 300J, and the low temperature toughness is good. Achieve the impact toughness requirements of the target.
