Abstract: A method for manufacturing a coated part having very high mechanical properties using hot forming techniques. The method includes: —providing an annealed steel strip or blank or pre-shaped part that was coated with a metal or metal alloy before the annealing —if a strip is provided, cutting a blank from the strip before or after the annealing —optionally forming a pre-shaped part from the blank —heating the blank or preshaped part to a temperature of 500° C. at an average heating rate of 16° C./s or more —further heating the blank or pre-shaped part to a temperature between 700 and 1000° C. —hot forming the blank or preshaped part into a hot formed part —hardening the hot formed part. A method for manufacturing a coated steel strip, blank or pre-shaped part, and a coated steel strip, blank or part and a hot formed part.

Abstract: A method for annealing a strip of steel having a variable thickness in its length direction with at least thicker and thinner sections, wherein the strip has been cold rolled to form the thicker and thinner sections, one thicker and one thinner section having a length of at most a few meter. The annealing is performed by continuous annealing.

Abstract: A strip of steel having a variable thickness in its length direction with at least thicker and thinner sections, the strip having been cold rolled to form the thicker and thinner sections, one thicker and one thinner section having a length of at most a few meters, which strip has been annealed. The annealing has been performed by continuous annealing.

Abstract: The invention relates to a method for producing a coated steel strip for producing tailored blanks suitable for thermomechanical shaping. The method includes the following steps: providing a hot-rolled steel strip; coating the strip with a metallic coating; cold rolling the strip such that the strip obtains a variable thickness in its length direction, having at least thicker sections and thinner sections, such that tailor rolled blanks (TRBs) can be cut from this strip. The invention also relates to a steel strip thus produced and the use of such a steel strip.

Abstract: Disclosed is a method for producing strip having a variable thickness in its length direction, in particular a repetitive thickness variation, using a stand of a rolling mill, wherein the strip has a thickness D1 when entering the mill stand and a thickness D2 when leaving the mill stand. The speed of the strip when leaving the mill stand is used as an input to control the speed of the rolls in the mill stand. Also disclosed is an apparatus for producing strip having a variable thickness.
