Abstract

Cette invention concerne un acier austénitique réfractaire et résistant aux hautes températures destiné à la fabrication d'articles utilisés dans les produits de combustion de carburants organiques fortement agressifs (mazouts à forte teneur en soufre, carbones, schistes, produits de craquage du pétrole et autres) et à des températures allant jusqu'à 650° C, notamment de tubes pour les surfaces de chauffage de surchauffeurs de vapeur. L'utilisation de cet acier à base de chrome et de manganèse permet d'accroître les caractéristiques de service de l'acier (résistance aux hautes températures, tant aux températures de travail que et notamment lors de démarrages-arrêts fréquents, augmentée plus de deux fois et plasticité en longueur de 35 à 40 %), sa fiabilité en exploitation et les ressources fonctionnelles d'au moins 2 à 3 fois. A cette fin, cet acier austénitique réfractaire et résistant aux hautes températures comprend du carbone, du chrome, du manganèse, du silicium, du nickel, du cuivre, du zirconium, du cérium, du titane, du niobium et du fer, et comprend également de l'aluminium et du bore. Ces composants sont choisis selon les proportions suivantes : de 0,05 à 0,15 % en poids de carbone ; de 1,0 à 2,0 % en poids de silicium ; de 8,0 à 16,0 % en poids de manganèse ; de 8,0 à 15,0 % en poids de chrome ; de 0,5 à 3,8 % en poids de nickel ; de 0,5 à 6,0 % en poids de cuivre ; de 0,01 à 0,09 % en poids de zirconium ; de 0,01 à 0,15 % en poids de cérium ; de 0,04 à 0,1 % en poids de titane ; de 0,2 à 3,0 % en poids de niobium ; de 0,01 à 0,25 % en poids d'aluminium ; de 0,001 à 0,08 % en poids de bore ; le reste se composant de fer et d'impuretés inévitables.
