Abstract
La présente invention concerne un acier inoxydable, ne comprenant pas d'éléments des terres rares coûteux qui ne simplifient pas la fabrication de l'acier. L'acier inoxydable selon l'invention possède une haute résistance à l'oxydation et une grande conductivité électrique, tout en présentant une faible vitesse de volatilisation du chrome (Cr) à haute température, ce qui fait qu'il est adapté pour être utilisé dans un matériau de connexion pour piles à combustible. L'acier inoxydable selon l'invention comprend : 20 à 35 % en poids de Cr; 1 % en poids ou moins de Mn; 0,3 à 5 % en poids de Nb, le reste étant constitué de fer et d'impuretés inévitables.
