DRAWING PROCESS AND WIRE OBTAINED BY THIS DRAWING PROCESS

摘要

The steel wire having a microstructure that is completely ferritic, a mixture of ferrite and cementite or a mixture of ferrite and perlite has a weight content of carbon C such that C < 0.05% 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.
