Abstract
A steel filament adapted for the reinforcement of elastomer or for thermoplastic products has a carbon content ranging up to 0.20 per cent by weight. The steel filament is provided with a coating promoting the adhesion with elastomer or thermoplastic products. The steel filament is drawn until a final diameter of less than 0.60 mm and a final tensile strength of more than 1200 MPa. Intermediate heat treatments are avoided so that the carbon footprint of the steel filament is substantially reduced.
