The steel wire having a completely ferritic, pearlitic or ferritic-pearlitic microstructure has a weight content of carbon C such that 0.05% C<0.4% and a weight content of chromium Cr such that Cr<12%. The process for drawing the wire comprises: at least one first uninterrupted series of steps (4001-400m) of drawing the wire from a diameter D to a diameter d′, at least one second uninterrupted series of steps (7001-700m) of drawing the wire of diameter d′ to a diameter d, one or more intermediate steps between the first and second uninterrupted series of steps (4001-400m, 7001-700m) of drawing the wire, the wire having a temperature less than or equal to 300° C. during the or each intermediate step.
