<p>A process of patenting at least one steel wire (10) with a diameter less than 2.8 mm. The cooling is alternatingly done by film boiling in water (14, 16) during one or more water cooling periods and in air during one or more air cooling periods. A water cooling period immediately follows an air cooling period and vice versa. The number of the water cooling periods, the number of the air cooling periods, the length of each water cooling period are so chosen so as to avoid the formation of martensite or bainite.</p> |
