Abstract

La présente invention concerne le domaine des alliages spéciaux résistant à la carburation. Les alliages contiennent, en poids : carbone 0,05 à 0,60 %; nickel 30 à 55 %; chrome 20 à 40 %; silicium 0,5 à 2 %; manganèse 0,5 à 2 %; azote 0,05 à 0,20 %; niobium 1 à 2 %; tungstène et/ou molybdène 0,2 à 5 %; aluminium 2 à 8 %; cuivre 0 à 5 %; fer et impuretés habituelles 0 à environ 46 %. Les alliages de l'invention sont notamment utiles pour constituer des éléments de structure de fours tubulaires d'installations pétrochimiques.
