Description
This paper investigates the effect of decarburization of a high-carbon steel wire rod with a 5.5-mm diameter on quality of drawn wire with a 1.2-mm diameter. A relationship was found between the depth of a decarburized layer in drawn wire and a wire rod and between this depth and fracture quality of wire in a torsion test. The second part of the investigation confirmed the application of pressure dies resulted in an average increase in the number of twists from 30% to 80% compared to minimal standard requirements
