Product Description

Mild steel SAE1018 1020/S20C SS400/S235JR A36 Cold drawn  round bar bright mild steel round bar manufacturer

Mild steel 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.
