\"C60-acier\"<\/a><\/p>\n

C60E \/ 1.1221 Acier sp\u00e9cial<\/b><\/strong>\u00a0est un acier d'ing\u00e9nierie non alli\u00e9 \u00e0 moyenne teneur en carbone qui contient du carbone 0.57%-0.65% selon la norme EN10083. Il pr\u00e9sente des caract\u00e9ristiques similaires \u00e0 celles de l'acier au carbone 1055 qui pr\u00e9sente une duret\u00e9 et une r\u00e9sistance \u00e9lev\u00e9es apr\u00e8s durcissement. et l'usinabilit\u00e9 est m\u00e9diocre en raison de la teneur \u00e9lev\u00e9e en carbone. Cet acier est g\u00e9n\u00e9ralement fourni dans un \u00e9tat non trait\u00e9 ou normalis\u00e9.<\/p>\n
