Wires of high speed and spring steels were drawn, after induction heating, at elevated temperatures. In order to analyse the wire drawing process at elevated temperatures, the drawing force and drawing temperature were measured; the drawing speed was constant. A new lubricant was developed. It allowed for greater reductions of area and a better surface quality. The mechanical properties of wires were determined after heating to elevated temperatures and then as drawn wires. Statistical analysis was applied for an estimation of the significance of die angle, single reductions and drawing temperature on the mechanical properties of wires and also on the drawing process as a whole. Drawing at elevated temperatures of high speed steel wire allowed for much improvement in the process as a result of an increase in the single draft area reductions and in the overall reduction; it eliminates also some of the intermediate heat and chemical treatments.
