1020 cold drawn steel round bar
Cold rolled 1020 steel bar is a low carbon steel grade with good weldability and formability for a various applications. 1018 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.
1020 cold drawn steel bar we supply includes following advantages:
|
Sizes |
Wide range from 14mm to 100mm |
|
Tolerances |
Precision to h9, h10, h11 or even small to 0.02mm |
