<p>Products with a long length starting are mfd. from a semi-finished prod. made in hot-rolled carbon steel. The semi-finished prod. is descaled and provided with a surface layer which will support a lubricant, after which it is cold-worked and then warm-worked at a temp. of 300-600 degrees C, the cold- and warm-working operations being alternated at least twice. The pref. amts. of plastic deformation are 40-50% during cold-working and 5-25% during warm-working. The process is used for mfr. of steel wire, strip and sections, and prevents micro-stresses and micro-fissures so that improved ductility and corrosion-resistance is obtd., e.g. a wire with optimum tensile strength and elongation.</p> |
