The invention relates to a steel and a processing method for higher-strength fracture-splittable machine components that are composed of at least two fracture-splittable parts. Said steel and method are characterized in that the chemical composition of the steel (expressed in percent by weight) is as follows: 0.40% <= C <= 0.60%; 0.20% <= Si <= 1.00%; 0.50% <= Mn <= 1.50%; 0% <= Cr <= 1.00%; 0% <= Ni <= 0.50%; 0% <= Mo <= 0.20%; 0% <= Nb <= 0.050%; 0% <= V <= 0.30%; 0% <= Al <= 0.05%; 0.005% <= N <= 0.020%, the rest being composed of iron and smelting-related impurities and residual matter.
L'invention concerne un acier et un procédé de transformation pour produire des pièces mécaniques pouvant être séparées par rupture présentant une résistance accrue, ces pièces étant constituées d'au moins deux parties pouvant être séparées par rupture. L'invention se caractérise en ce que la composition chimique de l'acier est la suivante (en pourcentage en poids) : 0,40% <= C <= 0,60%; 0,20% <= Si <= 1,00%; 0,50% <= Mn <= 1,50%; 0% <= Cr <= 1,00%; 0% <= Ni <= 0,50%; 0% <= Mo <= 0,20%; 0% <= Nb <= 0,050%; 0% <= V <= 0,30%; 0% <= AI <= 0,05%; 0,005% <= N <= 0,020%, le reste étant constitué de fer et des impuretés et résidus issus de la production de l'acier.
