Four low carbon steels were drawn from rod to wire on a commercial multi-die wire drawing machine. Samples were obtained from between dies. Internal damage, as a function of cold work, was determined using precision density measurements. Nitrogen was observed to have the greatest effect on the ductility of low carbon steel. Interstitial nitrogen causes internal damage, which results in wire breaks. The mobility of nitrogen increases with temperature, which could account for the increased probability of wire breaks at high drawing speeds.
