CA 2566144

A high temperature corrosion resistant stainless steel having a composition (by weight) of: C <= 0.2 %, but more than zero, N <= 0.1 % but more than zero, 0 <= 0.1 % but more than zero, Si <= 0.4 % but more than zero, Al <= 0.5 % but more than zero, Mn <= 0.5 % but more than zero, Cr 20 to 25 %, Ni <= 2.0 % but more than zero, Zr + Hf 0,01 to 0.1 %, Ti <= 0.5 % but more than zero, Mo + W <= 2.5 % but more than zero, Nb + Ta <= 1.25 % but more than zero, V <= 0.5 % but more than zero, and balance of Fe and naturally occurring impurities and not more than 0.010 % of S impurity. This steel is particularly suitable for the manufacturing of interconnects in solid oxide fuel cells.

L'invention concerne un acier inoxydable réfractaire résistant à la corrosion, qui présente la composition (en poids) suivante: C = 0,2 %, mais supérieur à zéro, N = 0,1 % mais supérieur à zéro, O = 0,1 % mais supérieur à zéro, Si = 0,4 % mais supérieur à zéro, Al = 0,5 % mais supérieur à zéro, Mn = 0,5 % mais supérieur à zéro, Cr 20 à 25 %, Ni = 2,0 % mais supérieur à zéro, Zr + Hf 0,01 à 0,1 %, Ti = 0,5 % mais supérieur à zéro, Mo + W = 2,5 % mais supérieur à zéro, Nb + Ta = 1,25 % mais supérieur à zéro, V = 0,5 % mais supérieur à zéro, le reste étant du Fe et des impuretés naturelles, avec 0,010 % au maximum d'impuretés S. Cet acier convient particulièrement bien à la fabrication d'interconnexions destinées à des piles à combustible à oxyde solide.
