In this study, a non-circular drawing (NCD) sequence was investigated for manufacturing high-strength and highductility pearlitic steel wires considering the effect of processing routes on occurrence of delamination fracture during the torsion test. For this purpose, the multi-pass NCD was conducted up to the 12th pass at room temperature with two kinds of processing routes, defined as the NCDA and NCDB. It was compared with the conventional wire drawing (WD). In the torsion test, delamination fracture was observed in the drawn wire by the WD for the 10th pass while it was not observed in the 12th pass NCDB. According to the X-ray diffraction measurement, a circular texture component, which increases likeliness of delamination fracture, was rarely observed in the drawn wire by the NCDB. From these results, it was demonstrated that the multi-pass NCDB could manufacture high-strength pearlitic steel wires with high-torsional ductility compared to the WD by reducing likeliness of delamination fracture.
