| 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. |
