Abstract
Improvements introduced in the manufacture of steels that, when hot, by cooling sufficiently fast from a sustenization temperature to obtain a martensitic microstructure and subsequent tempering at a temperature higher than 590º C, have sections that do not exceed 2, 5 cm an apparent limit of elasticity (permanent deformation, 0.2%) of more than 63 kg/mm2, a tensile strength of more than 70 kg/mm2, a ratio of the apparent limit of elasticity to the tensile strength of at least 0.8, a Charpy resilience with V notch of at least 5.5 mkg at room temperature and 3 mkg at -100º C, and good ductility and weldability, characterized by the fact that said steel contains 0, 14% to 0.24% carbon, 0.6% to 1.2% manganese, 0.10% to less than 0.5% silicon, 0.6% to 1.5% nickel, 0, 18% to 0.35% of chromium, 0.15% to 0.35% of molybdenum, 0.015% to 0.1% of aluminum and 0.0005% to 0.005% of boron, and the rest, except for ion of impurities, is iron.
