介绍了宝钢B610CF-L2与日本JFE公司JFE-HITEN610U2L低温调质高强钢板的力学性能及系列温度冲击性能的对比试验情况。结果表明,这两种钢板力学性能基本相当,均可满足设计温度为-50℃、2000 m3低温乙烯球罐的建造要求。
This paper introduces the comparison between the mechanical properties of Baosteel B610CF-L2 and JFE-HITEN610U2L high-temperature quenched and tempered high-strength steel plate made by Japan’s JFE Company and the series of temperature impact properties. The results show that the mechanical properties of the two kinds of steel plate are basically the same, which can meet the construction requirements of the low temperature polyethylene spherical tank with the designed temperature of -50 ℃ and 2000 m3.
