Abstract

<jats:p>The effect of areal reduction for one pass on mechanical properties of high carbon steel wire drawn using wet-type non-slip drawing machine was investigated. The wires of 0.443 mm in diameter with carbon 0.98% were drawn to 0.06 mm in diameter by reducing the sectional area of the wire by 14 % and 27 %. Tensile strength increased monotonically with increasing drawing strain and there were very few differences of tensile strength by pass schedule. Elongation had the minimum value at 2.5 of drawing strain and reduction of area also had the maximum value at 1.2 of drawing strain. Elongation and reduction of area were improved in the region of drawing strain more than about 3 by decreasing areal reduction for one pass. Therefore, the wire can be drawn with maintaining strength and ductility under small areal reduction for one pass at latter pass regardless of areal reduction at former passes.</jats:p>
