Abstract

L'acier utilisé pour produire des roues de véhicules sur rails, de préférence des roues de véhicules de chemins de fer, contient outre le fer 0,58 à 0,65 % en poids de carbone, 0,75 à 0,90 % en poids de manganèse, 0,25 à 0,40 % en poids de silicium, au maximum 0,008 % en poids de phosphore, au maximum 0,005 % en poids de soufre, 0,10 à 0,20 % en poids de nickel, 0,90 à 1,10 % en poids de chrome, 0,070 à 0,150 % en poids de molybdène, 0,070 à 0,120 % en poids de vanadium, au minimum 0,014 % en poids d'aluminium. Cet acier est thermiquement traité, étant premièrement chauffé jusqu'à une température comprise entre 800 et 815 °C pendant 4 à 5 heures, maintenu à cette température pendant 2 heures, puis refroidi pendant 120 à 150 secondes dans de l'eau en circulation à une température comprise entre 50 et 70 °C. On le laisse ensuite revenir pendant 4 à 4,5 heures à une température comprise entre 630 et 650 °C et on le refroidit définitivement à une vitesse de 50 °C par heure.
