摘要
对南钢试制的低碳、高铌、不添加钼成分的高温轧制(HTP)的X80管线钢钢板的性能进行了分析,针对其显微组织特点进行了详细的观察和研究,并对DWTT断口形貌、夹杂物以及第二相粒子的成分、尺寸及分布进行了分析,证实了采用HTP工艺技术生产的管线钢板完全能够达到X80的现行技术标准要求。
The paper analyzes mechanical properties of X80 pipeline steel plate trial-produced by high-temperature rolling processing (HTP) with the chemical composition of low-carbon, high niobium and without molybdenum. The observation and investigation focus on the characteristics of microstructures in detail, as well as the morphology of DWTT fracture, inclusions and precipitations. As is shown in the results, the properties of X80 pipeline steel plate made by HTP technology can all satisfy with the requirements o...
