Abstract

L'invention concerne un acier inoxydable austénitique offrant une excellente résistance à la corrosion fissurante sous tension (SCC) vis-à-vis de l'acide polythionique et une excellente ductilité au fluage. Selon le présent mode de réalisation, un acier inoxydable austénitique a une composition chimique contenant, exprimé en % en masse, 0,030 % maximum de C, 0,10 % maximum de Si, 0,20 à 2,00 % de Mn, 0,040 % maximum de P, 0,010 % maximum de S, 16,0 à 25,0 % de Ni, de 10,0 à 30,0 % de Cr, de 0,1 à 5,0 % de Mo, de 0,20 à 1,00 % de N, de 0,0005 à 0,100 % de Nb et de 0,0010 à 0,0080 % de V, le reste comportant du Fe et des impuretés, et satisfait à la formule (1). B +0 004-0,9 C +0 017 Mo 2 = 0 (1) Les symboles atomiques de la formule (1) sont ici substitués par la teneur (% en masse) de l'élément correspondant.
