摘要/Abstract

摘要： 抗硫管线钢主要用于加工石油、天然气的输送管道,对钢的强度、韧性、抗氢致裂纹(HIC)、抗硫应力腐蚀裂纹(SSC)和焊接性能等要求很高。结合石钢京诚生产抗硫管线钢的生产实践,对各成分的作用及影响进行了分析,并对抗硫管线钢KS30生产实践进行了介绍。在铁水P含量≤0.120%、铁水S含量≤0.050%的情况下,优选原辅料,可保证抗硫管线钢KS30成品P含量≤0.010%、S含量≤0.0015%、O含量≤0.0012%,轧材抗HIC、抗SSC性能全部合格

Abstract: Sulfur resistant pipeline steel is mainly used in the processing of petroleum and natural gas pipeline. It requires high strength and toughness of steel, anti hydrogen induced cracking(HIC) , anti sulfide stress corrosion cracking (SSC) and welding performance. Combining with the practice of Shi-Gang Jing-Cheng Equipment Development and Manufacturing Co Ltd, the role and influence of each element in steel have been analyzed, and the production practice of sulfur resistant pipeline steel KS30 is introduced. With molten iron P≤O.120% and S≤O.050% , optimizing raw materials and accessories, the sulfur resistant pipeline steel KS30 with P≤O.010% ,S≤O.0015% and O≤O.0012% is produced. The ability of anti-HIC and anti-SSC of rolled steel is all qualified.
