Definitions

  • the invention relates to a method of producing a part from a strip of rolled steel sheet and in particular hot rolled.
  • the object of the invention is to provide laminated steel sheets of 0.2 mm to about 20 mm thick, coated especially after hot rolling, and having to undergo shaping, either hot or cold followed by heat treatment, the temperature rise in front be ensured without decarburization of the 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 a hot-rolled sheet having a coating of metal or metal alloy deposited in surface, for the hot making of an intermetallic compound, the intermetallic compound ensuring corrosion protection, barrier against decarburization of sheet steel, lubrication during hot forming of the sheet, and on the finished part, after setting shape and cooling, mechanical hardness characteristics of high steel as well as a high surface hardness of the surface said finished part.
  • the invention also relates to the use of sheet metal in hot forming, in particular by stamping parts with high mechanical hardness characteristics and high surface hardness characteristics ensuring very good abrasion resistance.
  • stamping parts with high mechanical hardness characteristics and high surface hardness characteristics ensuring very good abrasion resistance.
  • the method according to the invention consists in coating a steel in particular hot rolled, for heat treatment and or hot forming, with a metal or a metal alloy such as aluminum or an alloy aluminum composed for example of aluminum and silicon.
  • the coating of metal or metal alloy is chosen so as to have corrosion protection and so as to withstand high temperature.
  • the coating forms an alloy layer with high resistance to corrosion, abrasion, wear and tiredness.
  • the coating does not modify the formability properties of steel and thus allows a wide variety of cold forming and hot.
  • the strip After hot rolling the strip can be pickled and rolled to cold before being coated. In the case where the sheet is cold rolled, that it can be annealed before being coated.
  • the sheet is subjected at a temperature rise preferably between 750 ° C and 1200 ° C in an oven with an atmosphere no longer requiring control due to the oxidation barrier formed by the coating. then as the temperature rises, the aluminum-based coating becomes transforms into an alloyed surface layer with different phases depending on the temperature treatment and having a high hardness can exceed 600 HV 100g.
  • the sheets supplied coated have significant resistance to corrosion during temperature increases, shaping, heat treatments, and when using finished formed parts.
  • the presence of the coating during heat treatments or hot forming avoids decarburization in addition to corrosion basic steel. This has an undeniable advantage in the case of an implementation hot formed for example in a stamping press. Indeed, the intermetallic alloy formed avoids, the formation of scale, the wear of tools by the scale, and therefore allows a longer life average of said tools. It has been noted that the intermetallic alloy formed hot, has a high temperature lubricant function. In addition, the effect protection against decarburization of the intermetallic alloy allows the use of a high temperature oven above 900 ° C with an atmosphere uncontrolled, even for several heating times hours.
  • the coating By the characteristics of the coating after raising temperature, the parts obtained have an increased resistance to fatigue, wear, abrasion and corrosion. In addition, the coating is weldable before and after temperature rise.
  • the sheet steel ensures, by cooling quenching effect, high mechanical characteristics of the part obtained after setting form, the coating transformed into a hot intermetallic alloy ensuring for its part, because of its qualities of lubricant and resistance friction, improved formatting, especially in the hot stamping field.
