Abstract
Pièces d'acier à haute résistance dont le procédé de formage consiste à produire une ébauche d'acier présentant une résistance à la rupture d'au moins environ 120 000 psi et une limite d'élasticité d'au moins environ 90 000 psi, et à la former à chaud de façon à obtenir une pièce de la configuration géométrique voulue présentant des caractéristiques de résistance sensiblement égales, ou même supérieures à celles de l'ébauche.
