  • Furnace for partially heating metal components
    Patent number: 11788164
    Abstract: A continuous furnace for the heat treatment of steel sheets, such as hot forming and press hardening, wherein two zones with mutually different temperatures are formed in the furnace, and a separating wall is present between the two zones. A gap is present in the closed state between the steel sheet and the separating wall and a surface cooling nozzle is in the form of a tube, wherein the surface cooling nozzle has outlet openings pointing downwards in the vertical direction and the surface cooling nozzle is arranged in the direction towards a relatively cooler zone.
    Type: Grant
    Filed: February 9, 2021
    Date of Patent: October 17, 2023
    Assignee: BENTELER AUTOMOBILTECHNIK GMBH
    Inventors: Viktor Glaser, Markus Wesling-Schaefers, Rainer Lapsien
  • Automotive component with enhanced strength
    Patent number: 11761069
    Abstract: An automotive component is produced by hot forming and press hardening a hardenable steel alloy having a tensile strength of at least 1700 MPa. The hardenable steel alloy, in addition to a balance made up of iron and melting-related impurities, has the following alloy elements carbon, niobium, and titanium. The automotive component is coated by a thermal coating process.
