Abstract

La présente addition concerne la fabrication de pivots pour liaisons à rotule. Cette fabrication consiste à choisir un acier à teneur en carbone de 0,30 à 0,45 % permettant une bonne trempe à coeur du pivot et un forgeage facile ainsi qu'une bonne possibilité de durcissement superficiel. Application à la réalisation de pivots.
