Patent number: 9090951Abstract: The invention relates to a method for the production of a hardened component made of a hardenable steel, wherein the steel strip is exposed to a temperature increase in an oven, and is thus exposed to an oxidizing treatment such that a surface oxide layer is created, and subsequently a coating using a metal or a metal alloy is carried out. The strip is heated and at least partially austenitized for producing an at least partially hardened component, and subsequently cooled and thereby hardened. The invention also relates to a steel strip produced according to said method.Type: GrantFiled: December 18, 2008Date of Patent: July 28, 2015Assignee: VOESTALPINE STAHL GMBHInventors: Werner Brandstätter, Siegfried Kolnberger, Thomas Kurz, Martin Peruzzi, Johann Strutzenberger, Thomas Manzenreiter

Patent number: 7938949Abstract: 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.Type: GrantFiled: November 1, 2010Date of Patent: May 10, 2011Assignee: voestalpine Stahl GmbHInventors: Werner Brandstatter, Herbert Eibensteiner, Martin Fleischanderl, Josef Faderl, Gerald Landl, Anna Elisabeth Raab, Siegfried Kolnberger
