Abstract
Cette invention concerne acier martensitique résistant à la chaleur pour chaudières, ayant une combinaison unique de résistance au fluage améliorée et d'une excellente résistance à l'oxydation lors d'une exposition à haute température dans des environnements contenant de la vapeur. Ledit acier présente l'analyse de fusion suivante (en pourcentage en poids) : C : 0,10 à 0,16 %, Si : 0,20 à 0,60 %, Mn : 0,30 à 0,80 %, P = 0, 020 %, S = 0,010 %, Al = 0,020 %, Cr : 10,5 à 12,00 %, Mo : 0,10 à 0,60 %, V : 0,15 à 0,30 %, Ni : 0,10 à 0,40 %, B : 0,008 à 0,015 %, N : 0,002 à 0,020 %, Co : 1,50 à 3,00 %, W : 1,50 à 2,50 %, Nb : 0,02 à 0,07 %, Ti : 0,001 à 0,020 %. Le reste de l'acier comprend du fer et les inévitables impuretés. L'acier est normalisé pendant une période d'environ 10 à environ 120 minutes dans la plage de températures allant de 1050 °C à 1170 °C et refroidi à l'air ou dans l'eau jusqu'à la température ambiante, puis revenu pendant au moins une heure dans la plage de températures allant de 750 °C à 820 °C. Il présente une microstructure martensitique ayant une teneur moyenne en ferrite delta inférieure à 5 % en volume.
