The invention relates to a method for drawing a steel wire, said method being applicable to a wire having a carbon level by mass C such that 0.05% < C < 0.4%, and an entirely ferritic, pearlitic or ferritic-pearlitic microstructure. The method comprises an uninterrupted series of steps (7001 - 700m) of drawing the wire of a diameter d' to a diameter d, d' and d being expressed in mm, wherein the rational deformation ε'=2.In (d'/d) is such that ε' > 4.
