Abstract (en)
[origin: WO2015075164A1] The invention relates to a steel wire comprising an entirely ferritic, pearlitic or ferritic-pearlitic microstructure, said steel wire having a carbon level by mass C such that 0.05% ≤ C < 0.4%, and a chromium level by mass Cr such that Cr < 12 %. The method for drawing the wire comprises: a first uninterrupted series of steps (4001 - 400m) of drawing the wire of a diameter D to a diameter d'; at least one second uninterrupted series of steps (7001 - 700m) of drawing the wire of a diameter d' to a diameter d; and at least one intermediate step between the first and second uninterrupted steps (4001 - 400m, 7001 - 700m) of drawing the wire, the wire having a temperature which is lower than or equal to 300°C during the or each intermediate step.
