A steel wire has a microstructure that is completely ferritic, a mixture of ferrite and cementite or a mixture of ferrite and pearlite and has a weight content of carbon C such that C&#x3c;0.05% and a weight content of chromium Cr such that Cr&#x3c;12%. The process for drawing the wire comprises: at least one first uninterrupted series of steps of drawing the wire from a diameter D to a diameter d', at least one second uninterrupted series of steps of drawing the wire of diameter d&#x2032; to a diameter d, and one or more intermediate steps between the first and second uninterrupted series of steps of drawing the wire, the wire having a temperature less than or equal to 300&#xb0; C. during the or each intermediate step.
