PROBLEM TO BE SOLVED: To provide a light-weight metal reinforcement body which has high mechanical strength, particularly, has resistant to corrosion.SOLUTION: A method of drawing a steel wire applies to a wire having a mass rate C of carbon such that 0.4%≤C≤0.74%. The method comprises uninterrupted series of steps (700-700) of drawing the wire from one diameter d' to another diameter d, d' and d being expressed in mm, in which true strain ε'=2In(d'/d) is such that ε'>4.SELECTED DRAWING: Figure 2

    【課題】機械的強度が高く、しかも特に腐食に耐性のある軽量の金属補強体を提供する。【解決手段】鋼鉄ワイヤを引き抜く方法が、0.4%≦C≦0.74%であるような炭素重量含有量Cを有するワイヤに適用される。本方法は、mm単位で表した直径d’から直径dまでの前記ワイヤの途切れのない一連の引き抜き工程(7001から700m)を含み、真歪ε’=2ln(d’/d)がε’>4であるようなものである。【選択図】図2
