<p>A process for manufacturing pearlitic steel wire, particularly with fine diameters and for use in reinforcing rubber vehicle tyres. The wire is subjected to a patenting treatment before being drawn to its final diameter, but is held at the transformation temperature for no more than 5 seconds after transformation has taken place. Such a step renders the wire capable of being subjected to true strains of more than 3.0 and achieving tensile strengths of 3000 Nmm-2 or more. The wire may be cooled from the transformation temperature via a first stage in which the temperature is reduced to 400 to 450°C over a period of time not less than 3 seconds.</p> |
