摘　　要：根据2011年国内外公布的高强度管线钢-平板、热轧板卷和无缝管的专利制造技术,慨述了抗大变形、优良低温韧性、耐腐蚀性管线钢的关键技术、组织和性能:高强度管线钢研发特点和趋势主要有:抗大变形管线钢-通过组织中弥散的M/A组元提高钢的强度;低温韧性钢-采用Mn-Nb-Mo合金化,通过控制轧制获得铁素体和/或贝氏体为主的组织;抗HIC(氢致裂纹)管线钢-控制C、P、Mn偏析引起的HIC的前提下,降低Nb、Ti含量,防止因Nb、Ti碳氮化物引起的氢致开裂。Based on published patented manufactured technologies for high strength pipeline steel including heavv plate, hot rolled coil and seamless tube at home and abroad in 2011, the key manufacturing technologies, structure and properties of pipeline steel with excellent anti-large-strain-deformation, low temperature toughness and corrosion resistance are summarized. The main R＆D characteristics and trend on high strength pipeline steel are excellent auti-large-strain-deformation steel- through dispersed M/A to increase strength of steel ; low temperature toughness steel- using Mn-Nb-Mo alloying and control rolling to get main ferrite and/or bainite structure; and anti-HIC （ hydrogen-induced cracking） pipeline steelwith prerequisite to control C, P, Mn segregation induced HIC, lowing Nb and Ti content in steel to prevent Nb, Ti carbo-nitride inducing hydrogen-induced cracking.
