Description
Wire rods with a diameter of 5.5 mm from two steel grades C52D2 (0.52%C) and C72DP (0.72%C) were drawn to a diameter of 1.35 mm in 13 draws and at two drawing speeds (0.5 m/s and 20 m/s). It was found that an increase in the speed of drawing significantly affects mechanical properties of drawn wire. One result observed in the final wire was a large drop in number of twists. The increase in speed also had an effect on the roughness of the wire surface–it became much smoother than after drawing at a low speed.
