s20c 1020 ss400 cold drawn hexagonal steel bar
Cold rolled SS400 s20c 1020 s235jr steel bar is a low carbon steel grade with good weldability and formability for a various applications. SS400 cold drawn steel bar are usually used in many industries like automotive, agriculture, construction and motorcycle.
Cold finished steel is cold drawn or cold rolled by hot rolled steel. It is typically produced as turned bars or cold drawn bars. Cold drawn steel bar is accomplished by cold drawing a bar through a mould. By cold drawing, the dimensional tolerances, the straightness and the surface roughness of the bars will be improved. In the meanwhile, the mechanical properties will be enhanced, too.
