摘要:
概述了日本JFE公司开发的低温韧性优良的X80电阻焊（ＨＦW）管线钢管的性能和特点。为了提高天然气和石油的输送效率，厚壁高强度的管线钢管逐渐被应用于高压管线的敷设。为进一步提高X80管线钢管用热轧卷板性能，研究了热轧卷板的组织、化学成分对强度和韧性的影响。在此研究基础上，JFE公司采用TMCP轧制工艺开发了具有细化析出物、没有珠光体或马氏体组织的超低碳贝氏体铁素体钢。采用所开发的钢制成的ＨＦW管线钢管因其母材和焊缝具有良好的匹配性能，特别适用于低温环境。
Abstract:
This paper introduces nature and characteristics of the X80 grade electric resistance welding(ＨＦW) line pipe developed by Japan JFE Steel.In order to improve transporting efficiency for natural gas and oil,thickwalled high strength line pipes are to be increasingly used for high pressure pipeline laying.The effects of microstructure and chemical composition on strength and toughness were researched for improving the material properties of hot rolled coil used for X80 grade pipeline steel pipe.Based on the result,JFE Steel has developed ultra low carbon bainitic ferrite steel with fine precipitates and no coarse pearlite or martensite by adopting thermomechanical controlled process(TMCP).ＨＦW linepipe is suitable for low temperature produced by ultra low carbon bainitic ferrite steel because of good matching performance of base material and weld.
