Abstract

L'invention concerne un alliage Ni-Fe-Cr présentant une excellente résistance à la corrosion intergranulaire. Dans un mode de réalisation, l'alliage Ni-Fe-Cr présente une composition chimique contenant, en % en masse : 0 005-0 015 % de C, 0,05-0,50 % de Si, 0,05-1,5 % de Mn, 0 030 % ou moins de P, 0 020 % ou moins de S, 1,0-5,0 % de Cu, 30,0-45,0 % de Ni, 18,0-30,0 % de Cr, 2,0-4,5 % de Mo, 0,5-2,0 % de Ti, 0,001-0,015 % de N et 0-0,50 % d'Al, le reste étant constitué de Fe et d'impuretés. Le diamètre moyen de grain cristallin d (µm) satisfait l'expression (1). d<4.386/(Crel+0.15) (1) Crel dans l'expression (1) est défini par l'équation (2) Crel=C-0.125Ti+0.8571N (2). Dans les divers symboles d'élément de l'expression (1) et l'équation (2), la teneur (% en masse) de l'élément correspondant doit être substituée.
