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.
