Formules m\u00e9tallurgiquement pour offrir une r\u00e9sistance \u00e9lev\u00e9e \u00e0 l’oxydation dans les environnements thermiques exigeants, les cylindres en acier \u00e0 haute teneur en chrome de DURON (Cylindres HCrS) b\u00e9n\u00e9ficient d’une composition optimis\u00e9e. En int\u00e9grant une plage de carbone sp\u00e9cifique \u00e0 des niveaux \u00e9lev\u00e9s de chrome et de molybd\u00e8ne, nous optimisons la pr\u00e9cipitation de carbures r\u00e9sistants \u00e0 l’usure sans sacrifier la t\u00e9nacit\u00e9 structurelle du noyau. Cette composition contr\u00f4l\u00e9e permet \u00e0 ces cylindres sp\u00e9cialis\u00e9s en acier au chrome de maintenir une duret\u00e9 \u00e0 chaud \u00e9lev\u00e9e et des performances stables sous l’effet de frictions cycliques.
