1. cold drawn steel bar

CD bar is a low carbon steel with a medium manganese content. Has good case hardening properties, fair machinability and is excellent for cold bending and forming operations. Readily welded and brazed.

2.Cold drawn steel bar Typical applications

Suitable for general shafting purposes and for applications that do not require the greater strength of high carbon and alloy steels.

3. cold drawn steel bar main type and avaliable sizes
 

Round bars	5mm-130mm
Suqare bar	6*6mm-100*100mm
Flat bars	3mm*20mm-50mm*100mm
Hex bars	6mm-100mm
Bar Finsihe	Peeled, Cold Drawn, TurnedTurned & Polished, Centreless Ground

4. Cold drawn steel bar size tolerance

h9,h10,h11 or other tolerance according to client's requirement
