Acier d’outillage pour travail à froid

À mesure que les exigences concernant les aciers deviennent plus strictes, choisir l’acier d’outillage le mieux adapté à l’application donnée est de plus en plus important. Mais quelles sont ces exigences ? L’outil fabriqué doit posséder une résistance à l’usure suffisante. Il doit fonctionner en toute fiabilité, sans défaillances imputable à un écaillage, une fissuration, ou une déformation plastique prématurés. La rentabilité optimale – soit le coût le plus faible possible par outil produit (maintenance comprise) – ne peut être obtenue qu’en choisissant l’acier adéquat pour l’application donnée.
