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.
