Definitions

  • the thickness of the steel sheet used in the process according to the invention is preferably between 0.5 and 4 mm, thickness range used in particular in the manufacture of structural parts or reinforcement for the automotive industry. . This can be obtained by hot rolling or subsequent cold rolling and annealing. This thickness range is suitable for industrial press hardening tools, especially hot stamping presses.
  • the inventors have sought the conditions which make it possible to avoid the delayed cracking of parts with very high mechanical strength hardened under press. It will be recalled that this process is characterized by the fact that blanks of steel, bare or pre-coated with a metal coating (aluminum or aluminum alloy, zinc or zinc alloy), are heated. here being then transferred to a hot stamping press. During the heating step, the water vapor possibly present in a smaller quantity in the oven is adsorbed on the surface of the blank. Hydrogen from the dissociation of water can be dissolved in the austenitic steel substrate at high temperature. The introduction of hydrogen is thus facilitated by an oven atmosphere with a high dew point, a high austenitization temperature and a long holding time.
  • a metal coating aluminum or aluminum alloy, zinc or zinc alloy
