Con\u00e7us pour des applications intensives exigeant une int\u00e9grit\u00e9 structurelle exceptionnelle, les cylindres en fonte nodulaire perlitique de DURON (Cylindres SGP) pr\u00e9sentent une matrice perlitique stable avec du graphite sph\u00e9ro\u00efdal. Cette pr\u00e9cision m\u00e9tallurgique offre une r\u00e9sistance \u00e9lev\u00e9e \u00e0 la traction, une durabilit\u00e9 profonde des cannelures et une r\u00e9sistance sup\u00e9rieure au craquelage thermique ainsi qu’aux chocs m\u00e9caniques. Nous optimisons la transformation perlitique par un contr\u00f4le pr\u00e9cis des \u00e9l\u00e9ments d’alliage afin de garantir des performances constantes de la surface jusqu’au c\u0153ur du cylindre. Les compositions chimiques et les sp\u00e9cifications m\u00e9tallurgiques de ces cylindres en fonte nodulaire perlitique sont d\u00e9taill\u00e9es ci-dessous : <\/p>\n\n
