Product Description

4140 cold drawn steel round bar


4140 steel is a Chromium-Molybdenum through-hardening steel of medium hardenability. It is a general purpose high-tensile steel with medium strength level and good impact properties.

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.

4140 cold drawn steel bar we supply includes following advantages:

Consistent mechanical properties

Deep mechanical properties (from surface to the center according to your requirement)

Even hardness on the whole bars/Tougher and Increased strength

No brittle, UT testing/Precision size tolerance/Good straightness

Good Roughness/Professional technical service/Competitive price/Fast delivery
