Abstract

La présente invention est relative à un alliage pour le traitement désoxydant de l'acier. L'alliage en question comprend : de 1 à 10 % en poids de calcium, de 3 à 20 % en poids de silicium, le reste étant de l'aluminum. L'alliage selon l'invention est utile pour le traitement des aciers dont il améliore les qualités, notamment la stabilité au vieillissement sans altérer les qualités mécaniques.
