Title (EN) HIGH-CARBON STEEL WIRE OR STEEL THEREFOR EXCELLENT IN WORKABILITY IN WIRE DRAWING AND PROCESS FOR PRODUCING THE SAME
(FR) FIL D'ACIER A HAUTE TENEUR EN CARBONE OU ACIER CONSTITUANT UN TEL FIL, PRESENTANT UNE EXCELLENTE APTITUDE AU TREFILAGE, ET SON PROCEDE DE FABRICATION
Abstract: front page image
(EN)A high-carbon steel wire or steel therefor excellent in workability in wire drawing and a process for producing the same. The wire contains on the weight basis 0.90-1.10 % of carbon, not more than 0.40 % of silicon and not more than 0.50 % of manganese; not more than 0.02 % of phosphorus, not more than 0.01 % of sulfur and not more than 0.003 % of aluminum; and the balance consisting of iron and inevitable impurities. Further it has a microstructure wherein the area rate of the upper bainite structure formed by two-stage transformation is 80 % or above and the Hv value is 450 or less. It may further contain 0.10-0.30 % of chromium as the alloying component.
(FR)Le fil d'acier selon l'invention contient, en pour-cent en poids, 0,90-1,10 % de carbone, au maximum 0,40 % de silicium et au maximum 0,50 % de manganèse; au maximum 0,02 % de phosphore, au maximum 0,01 % de soufre et au maximum 0,003 % d'aluminium; le reste étant constitué de fer et des impuretés inévitables. Un tel fil présente, en outre, une microstructure dont le rapport surfacique de la structure bénitique supérieure constituée par transformation en deux étapes est de 80 % au minimum et la valeur Hv est de 450 au maximum. Ce fil peut également contenir 0,10 à 0,30 % de chrome comme composant d'alliage.
