Definitions

  • the invention relates to a method for producing a part with very high mechanical characteristics, shaped by stamping, from a strip of rolled steel sheet, in particular hot rolled and coated with a metal or a metal alloy providing surface and steel protection.
  • the heat treatment must be carried out under a controlled atmosphere in order to avoid any decarburization and oxidation of the steel.
  • the scale by its abrasive power, damages the forming tools, which reduces the quality of the parts obtained from the dimensional and aesthetic point of view or requires frequent and costly repairs. of tools.
  • the parts thus obtained must receive an expensive post-treatment, the application of which is difficult, if not impossible, in particular in the case of parts comprising recesses.
  • the post-coatings of steels with very high mechanical characteristics also have the disadvantage of creating risks of embrittlement by hydrogen in electro-galvanizing techniques or of modifying the mechanical properties of these steels in techniques of galvanizing by dipping of previously formed parts.
  • the object of the invention is to provide users with laminated steel sheets from 0.2 mm to around 4 mm thick, coated in particular after hot rolling, and having to undergo a shaping, either hot or cold followed by a treatment thermal, as well as a method of producing a part by hot forming, from these coated steel sheets, the temperature rise being ensured without decarburization sheet steel, without oxidation of the surface of said sheet, before, during and after hot forming and or heat treatment.
  • the invention also relates to the use of a strip of laminated steel sheet and in particular hot rolled and coated with a metal or a metal alloy ensuring protection of the surface and the steel of the sheet in forming by especially hot stamping of parts, the parts having high mechanical characteristics in hardness and high hardness characteristics in surface as well as very good abrasion resistance.

  • Figures 4a and 4b are sectional photographs of part of a room, having a zinc aluminum coating produced according to the invention, before and after heat treatment.
  • the method according to the invention as presented in the diagram of FIG. 1, consists, from a sheet of steel for heat treatment and or hot forming especially hot rolled and coated with zinc or a zinc-based alloy, production of a hot-formed part using a tool such as a press stamping.
  • the zinc or zinc alloy coating is chosen so as to generate a protection against corrosion of the base sheet, in coil.
  • the coating forms a layer which combines with the steel of the strip and at this time exhibits an outfit mechanical avoiding the melting of coating metal.
  • the compound formed has a high resistance to corrosion, abrasion, wear and fatigue.
  • the coating does not modify the formability properties of steel and thus allows great variety of cold and hot shaping.
  • the strip After hot rolling, the strip can be pickled and cold rolled before to be clothed. In the case where the sheet is cold rolled, it can be annealed before to be clothed.
  • the laminated sheet can be coated, for example, with zinc, or zinc alloys aluminum.
  • the sheet can be stamped at cold to obtain the part.
  • the part obtained is then subjected to a treatment.

  • the presence of the coating during heat treatments or forming hot prevents decarburization of the base steel. That to an undeniable advantage in the case of hot shaping for example in a stamping press.
  • the intermetallic alloy formed avoids, the formation scale, wear of tools by scale, and thus allows an elongation of the average life of said tools.
  • the intermetallic alloy formed at hot has a high temperature lubricant function.
  • the protective effect against decarburization of the intermetallic alloy allows the use of high furnace temperature exceeding 900 ° C with an uncontrolled atmosphere, even for heating times of several minutes.
  • the parts obtained Due to the characteristics of the coating after temperature rise, the parts obtained have increased resistance to fatigue, wear, abrasion and corrosion, including on edge due to the galvanic behavior of zinc with steel.
