SD Steel Successfully Developed Hot-Rolled Coils of Pipeline Steel Resistant to Large Deformation

Recently, Rizhao Company successfully developed hot-rolled coils of pipeline steel with large deformation resistance. This new product not only fills the gap in the industry but also has broad sales market prospects.
The hot-rolled coil of pipeline steel is resistant to large deformation and has excellent performance. On the basis of high strength and toughness, it has the characteristics of a low yield ratio and high uniform deformation elongation, which can meet the service requirements in polar regions, frozen soil, seismic zones, and other areas.
Rizhao Company's hot-rolled product research and development team combined user requirements, innovated the composition system, optimized the cooling process, and overcame the problem of precise control of low-temperature coiling temperature. They successfully developed wide and thick specifications of hot-rolled pipeline steel coils that are resistant to large deformation and achieved industrial application in a key domestic gas pipeline project.
