Abstract

La présente invention décrit un alliage résistant à la chaleur ne possédant pas le défaut d'arracher les écailles formées sur la surface de l'acier pendant le traitement thermique. Cet alliage a la composition pondérale suivante : C 01-0,5 %, Si 1 à 1,8 %, Mn jusqu'à 2 %, Cr 26 à 30 %, Ni 34 à 40 %, Co minimum 3 %-maximum 10 %, Ni + Co minimum 37 %, maximum 43 %, Mo 0,5 à 3 %, Nb 0,5 à 5 %, W 0,5 à 10 %, P jusqu'à 0,04 %, S jusqu'à 0,04 % et le reste est Fe. Utilisatton de ces alliages pour des structures placées à l'intérieur de fours métallurgiques.
