Example: Drawing of stainless wire www.metalwire-mesh.com • Larger diameter stainless wire is first surface examined, tensile and hardness tested, diameter size measured. • Surface preparation by pickling in acid (ferrictic and martensitic steels) and basic solutions (austenitic steels). The prepared skin is then coated with lubricant. • Cold drawing is carried out through diamond dies or tungsten carbide dies till the desired diameter is obtained. • Stainless steels: 304, 304L, 316, 316L • Applications: redrawing, mesh weaving, soft pipe, steel rope, filter elements, making of spring. www.metalwiremesh.com Stainless steel rope • Cleaning off oil/lubricant is then carried out and the wire is heat-treated (annealing at about 1100 o C or plus skin pass).

Stepped-cone multiple-pass wiredrawing • More economical design. • Use a single electrical motor to drive a series of stepped cones. • The diameter of each cone is designed to produce a peripheral speed equivalent to a certain size reduction.
