Abstract
The steel wire of diameter d expressed in mm has a completely ferritic, pearlitic or ferritic-pearlitic microstructure and a weight content of carbon C such that 0.05%≦C<0.4%, a weight content of chromium Cr such that Cr<12% and a maximum tensile strength R, expressed in MPa, such that R≧175+930.C−600.In(d) and R≧1500 MPa.
