Abstract

L'invention est relative à des perfectionnements aux alliages ferreux. Ces alliages comportent en % en poids, 17 à 23 % de manganèse, plus de 6 et moins de 10 % de chrome, jusqu'à 0,8 % de carbone, jusqu'à 1,5 % de silicium, jusqu'à 0,8 % d'azote, jusqu'à 2,75 % de nickel, jusqu'à 3,5 % de molybdène, jusqu'à 1,7 % de vanadium, jusqu'à 0,45 % de columbium, le restant étant du fer, la somme manganèse + chrome étant supérieure à 24 et inférieure à 31,5 et la somme carbone + azote étant comprise entre 0,35 et 0,8. Utilisation particulièrement intéressante pour des couronnes de retenue et des anneaux déflecteurs dans les générateurs électriques de grandes dimensions.
