摘要
通过收集芜湖长江大桥采用的14MnNbq钢4万余吨钢材的质保书,采用数理统计的方法对其主要化学成分、机械性能进行了分析研究,同时与其他桥梁采用的日本和韩国生产的SM490C桥梁钢进行了比较、分析,表明14MnNbq钢的综合性能是优异的。
The author collected the quality assurance certificates of the 40 thousand ton 14MnNbq steel adopted by the Wuhu Yangtze River Bridge, and then analyzed and studied the chemical composition and mechanical performance of the 14MnNbq steel with mathematical statistics method. The results of analysis and comparison with the SM490C steel of other bridges imported from Japan and South Korea indicate excellent performance of the 14MnNbq steel
