Cold drawing is utilized to improve the mechanical properties of steel bar products. The hot rolled steel is drawn through a sequence of reducing dies or rollers that coldwork the steel into a strand hardened form, improving mechanical properties. It also allows the processor to greatly improve the dimensional tolerance of the product being made.
