Abstract

Cette pièce mécanique en acier est issue de la forge à chaud ou de la frappe à froid. De taille moyenne ou petite, elle vient de la transformation plastique d'un demi-produit sidérurgique long issu de la coulée continue et laminé à chaud dans le domaine austénitique puis mis en forme par déformation plastique et traité thermiquement pour obtenir une structure métallographique contenant essentiellement de la ferrite aciculaire au moins dans les zones de sollicitations mécaniques en ténacité et en fatigue. La composition dudit acier, outre le fer et les inévitables impuretés résiduelles résultant de l'élaboration de l'acier, répond au moins à l'analyse suivante: entre 0,2 et 0,5 % de C; 0,5 et 2,0 % de Mn; entre 0, 05 et 0, 5 % de V; entre 0, 6 et 1,5 % de Si; entre 0,05 et 1,0 % de Cr, entre 0,01 et 0,5 % de Mo; entre 0,02 et 0,10 de S, de préférence entre 0,01 à 0,02 % de Ti et/ou jusqu'à 0,20 % d'Al, et entre 5 et 30 ppm de Ca.
