Abstract (en)

[origin: CA2666677A1] The invention relates to a steel and a processing method for higher-stren gth 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% <= A l <= 0.05%; 0.005% <= N <= 0.020%, the rest being composed of iron and smelting-related impurities and residual matter.
