  • Patent number: 9228148
    Abstract: A method of producing shaped articles made from single-sidedly or double-sidedly galvanized steel sheet, starting from galvanized steel strip, at least one of the steps of the method being a transport operation, and in which, for protection from black-spot corrosion, a corrosion preventive oil is applied which comprises at least one phosphoric acid polyoxyalkylene ester.
    Type: Grant

  • Patent number: 8181331
    Abstract: The invention relates to a method for producing hardened structural parts from sheet steel. The method includes shaping at least one shaped part made of sheet steel provided with a cathodic corrosion protection coating, performing any required final trim of the shaped part and possibly any required punching, or the creation of a perforation pattern, subsequently heating the shaped part, at least over partial areas, under the admission of atmospheric oxygen to a temperature which permits austenizing of the steel material, and thereafter transferring the structural part to a mold-hardening tool and performing mold-hardening in the mold-hardening tool, wherein the structural part is cooled by the contact with and pressing by the mold-hardening tool and is hardened thereby.

  • Patent number: 8021497
    Abstract: The invention relates to a method for producing a hardened steel part having a cathodic corrosion protection, whereby a) a coating is applied to a sheet made of a hardenable steel alloy in a continuous coating process; b) the coating is essentially comprised of zinc; c) the coating additionally contains one or more oxygen-affine elements in a total amount of 0.1% by weight to 15% by weight with regard to the entire coating; d) the coated steel sheet is then, at least in partial areas and with the admission of atmospheric oxygen, brought to a temperature necessary for hardening and is heated until it undergoes a microstructural change necessary for hardening, whereby; e) a superficial skin is formed on the coating from an oxide of the oxygen-affine element(s), and; f) the sheet is shaped before or after heating, and; g) the sheet is cooled after sufficient heating, whereby the cooling rate is calculated in order to achieve a hardening of the sheet alloy.

  • Patent number: 7938949
    Abstract: The invention relates to a method for producing a hardened profiled structural part from a hardenable steel alloy with cathodic corrosion protection. The method includes applying a coating to a sheet made of a hardenable steel alloy, wherein the coating comprises zinc, and the coating further comprises one or several elements with affinity to oxygen in a total amount of 0.1 weight-% to 15 weight-% in relation to the total coating. After applying the coating, the coated sheet steel is roller-profiled in a profiling device, so that the sheet tape is formed into a roller-formed profiled strand. Thereafter, the coated sheet steel is brought, at least in parts and with the admission of atmospheric oxygen, to a temperature required for hardening and is heated to a structural change required for hardening. A skin made of an oxide of the element(s) with affinity to oxygen is formed on the surface of the coating.
