Non-trivial changes in physical and mechanical properties and structure of low carbon steel wire, produced by rolling with shear and cold drawing


The hereditary influence of the initial wire rod structure on the structure and physical-mechanical properties of the steel wire 08G2S, manufactured by rolling with shear, combined with the cold drawing is investigated. For comparison, the structure and properties of samples of the same steel wire, produced by commercial technology of rolling and drawing, were investigated. It has been shown that formation of the special structural state of low carbon steel by rolling with shear provides the increasing of the ductility and electric conductivity of wire in combination with satisfactory technological plasticity.
