Abstract
L'invention concerne un acier inoxydable austénitique qui présente une excellente résistance à la carburation même dans un environnement de carburation à haute température et qui présente également une excellente aptitude à l'ouvrabilité à chaud pendant la production. Un acier inoxydable austénitique selon un mode de réalisation de la présente invention présente une composition chimique qui contient, en % en masse, 0,03 % ou plus mais moins de 0,25 % de C, 0,01 % à 2,0 % de Si, 2,0 % ou moins de Mn, 10 % ou plus mais moins de 22 % de Cr, plus de 30,0 % mais 40,0 % ou moins de Ni, plus de 2,5 % mais moins de 4,5 % d'Al, 0,01 % à 3,5 % de Nb, 0,0005 % à 0,05 % de Ca, 0,0005 % à 0,05 % de Mg et 0,03 % ou moins de N, le reste étant constitué de Fe et d'impuretés. La concentration en Cr CCr' de la couche superficielle de cet acier inoxydable austénitique et la concentration en Al CAl' de la couche superficielle de cet acier inoxydable austénitique satisfont à la formule (1) par rapport à la concentration en Cr CCr de portions autres que la couche superficielle et la concentration en Al CAl de portions autres que la couche superficielle. 0,40 = (CCr'/CAl')/(CCr/CAl) = 0,80 (1)
