Abstract

La presente invención se refiere a un resorte (3´) y/o a una barra de torsión (3´´) fabricados a partir de un alambre de acero (1) mediante conformación en frío (20´, 20´´) según un procedimiento con los siguientes pasos: a) facilitación de un alambre de acero (1); b) conformación termomecánica (12) del alambre de acero (1) facilitado en el paso a) por encima de la temperatura de recristalización mínima del alambre de acero (i); c) enfriamiento del alambre de acero (1) conformado termomecánicamente en el paso b); d) bonificación del alambre de acero (1), que comprende I. Calentamiento (17); II. Templado (18); III. Recalentamiento; IV. Enfriamiento; e) conformación en frío (20´, 20´´) del alambre de acero (1) bonificado en el paso d), a una temperatura de conformación en frío, siendo la temperatura de conformación en frío una temperatura por debajo de la temperatura de recristalización mínima del alambre de acero (1); f) separación (21) del alambre de acero (1) conformado en frío en el paso e) ; enfriándose de tal forma durante el enfriamiento del alambre de acero (1) en el paso c) a una temperatura por debajo de la temperatura de recristalización mínima, que en el alambre de acero (1) se produce al menos una estructura parcialmente ferrítica-perlítica.
