Method for hot forming a coated metal part and formed part

Method for manufacturing a coated part having very high mechanical properties using hot forming techniques, comprising the following steps:

• 1. providing an annealed steel strip or blank or pre-shaped part that has been coated with zinc or a zinc alloy before the annealing
• 2. if a strip is provided, cutting a blank from the strip before or after the annealing
• 3. optionally forming a pre-shaped part from the blank
• 4. heating the blank or pre-shaped part to a temperature of 500° C. at an average heating rate of 16° C./s or more
• 5. further heating the blank or pre-shaped part to a temperature between 700 and 1000° C.
• 6. hot forming the blank or pre-shaped part into a hot formed part
• 7. hardening the hot formed part,
• wherein before the blank or pre-shaped part is taken out of an oven and put in a hot-forming apparatus, the heating of the blank or pre-shaped part is performed within 3 minutes.
