The Research and Trial Manufactue of Hot-Relled Wire H08MnSiCrNi For Making Climate-Protecting Welding Wire

摘要

The article introduced the whole process of the research and the trial manufacture of hot-rolled wire H08MnSiCuCrNi for making climate-protecting welding wire, which include the designing of chemical content, steel making, steel rolling process. Their influence to the process in further working and to the property of the final product welding wire was analysed through experiment. And the final product climate-protecting welding wire was appraised by the Railway Ministry of China.
