Development of H08MnMoTiB Submerged Arc Welding Wire Steel for Oil Pipeline |
| |
| Abstract: | The H08MnMoTiB submerged arc welding wire steel for oil pipeline in Beiying Steelmaking Plant of Benxi Iron & Steel Group Company was developed by taking such measures as hot metal desulphurization, accurately controlling the end point of steelmaking by convertor and chemical compositions in electric furnace as well as using the technology for controlling the content of gas and non-metallic inclusions during the smelting. The testing results show that the macrostructure in a steel billet and the surface quality of the billet are good. The microstructures of the steel wire rods produced by using such a steel billet are homogeneous and the quality of these rods is stable. |
