Abstract
The process for drawing a steel wire applies to a wire having a carbon content by weight C such that 0.4%≦C≦0.74%. The process comprises an uninterrupted series of drawing steps (7001-700m) of the wire from a diameter d′ to a diameter d, d′ and d being expressed in mm, in which the true strain ε′=2.ln(d′/d) is such that ε′>4.

A process for drawing a steel wire, the process comprising steps of:
- providing a steel wire having a carbon content by weight C of 0.4%≦C≦0.74%;
- and
- drawing the steel wire in an uninterrupted series of drawing procedures, such that the steel wire is drawn from a diameter d′ to a diameter d,
- wherein d′ and d are expressed in mm, and
- wherein a true strain ε′ of the steel wire is given by ε′=2.ln(d′/d), with ε′>4.
