If the reduction in diameter is greater than 50%, the process may require patenting between the processes of drawing the
wire through the dies. Patenting is done to release the stress which is induced during drawing operations. Commercial wire
drawing usually starts with a coil of hot rolled 11–9 mm diameter wire rod.
Steel wires produced by cold drawing are used in many critical engineering applications such as motor tyre beed,
electrodes, springs, wire ropes, mesh, and so forth [1,2]. In general, steel wires are produced from control cooled or patented
wire rods by single or multi pass cold drawing operations. During cold drawing, wire breakages sometimes occur, causing
operational interruptions and loss of productivity [3–6]. The types of wire breakages that occur during cold drawing may be
attributed by improper input wire rod quality in terms of microstructure and cleanliness, inappropriate combinations of
