The effect of a real reduction for one pass on mechanical properties of high carbon steel wires 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 under 14 % and 27 % of areal reduction for one pass. Tensile strength, total elongation and reduction of area were measured, then each behavior against drawing strain and the difference by areal reduction for one pass were clarified. Tensile strength increased monotonically with increasing drawing strain and there were very few differences of tensile strength by pass schedule. The value of elongation was minimum at 3.0 of drawing strain whiles the reduction of area was maximum at 1.2 of drawing strain. Elongation and reduction of area were improved by decreasing areal reduction for one pass at more than about 3.0 of drawing strain. Therefore, the wires could be drawn with maintaining strength and ductility under small areal reduction for one pass at latter passes regardless of areal reduction at former passes.
