Beschreibung
Zusammenfassung:	The invention relates to a steel-based metal wire for reinforcing rubber items selected from among vehicle tyres, tracks and conveyor belts which is obtained by means of a method comprising at least one step of producing a steel wire, referred to as a "wire rod", with a diameter ranging from 4.5 to 6.5 mm based on a feedstock comprising at least 70 wt% recycled steel, the steel of the wire rod having a nitrogen content of at least 70 ppm, and a step of decreasing the diameter of the wire rod from a diameter d to a diameter d1.
