  • Patent number: 10151009
    Abstract: A method for producing a structural and/or safety-related motor vehicle component having at least one hot-formed and press-hardened part constructed from high-strength steel includes the steps of partially heat-treating a region of the motor vehicle component by heating the region to a heat-up temperature in a temperature range between 500° C. and 900° C.; maintaining the heat-up temperature for a duration of a holding time; and cooling down from the heat-up temperature in one or more phases. A body component constructed as a structural and/or safety-related motor vehicle component from a steel sheet blank that has been hot-formed and press-hardened includes joining flanges and/or coupling locations and/or safety-related parts, wherein the joining flanges, coupling locations and/or safety-related parts are partially heat-treated in several steps with the disclosed method.

  • Publication number: 20100300584
    Abstract: According to the method, a blank (7) that is severed from strip material (4) of coated, high-strength boron steel is homogeneously heated in a furnace (11) having a plurality of temperature zones (8, 9, 10) first in a 1st zone (8) to a temperature of approximately 830° C. to 950° C. and maintained at this temperature level for a defined time (t). Thereafter, a region (12) of first kind of the blank (7) is cooled down in a 2nd zone (9) of the furnace (11) to a temperature of approximately 550° C. to 700° C. and maintained at this lowered temperature level for a defined time (t1). At the same time, a region (13) of second kind of the blank (7) is maintained in a 3rd zone (10) of the furnace (11) at a temperature level of approximately 830° C. to 950° C. during a time (t2). After this heat treatment, a blank (7) is formed into a shaped component (1) in a thermoforming process.
