Abstract
L'invention est du domaine des alliages d'acier. Elle vise plus précisément des aciers alliés renfermant de l'ordre de 0,30 à 0,5 % de carbone, de 18 à 23 % de nickel, de 20 à 24 % de chrome, de 5 à 13 % de cobalt et du niobium à raison de 4,5 à 5,5 fois la teneur en carbone, le reste étant du fer, et éventuellement du silicium et du manganèse. Applications industrielles dans des domaines de températures où une résistance à la corrosion est nécessaire.
