    摘要： The invention relates to a. method for manufacturing a coated steel part having very high mechanical properties using hot forming techniques.
    According to the invention, the method comprises the following steps:
    • providing a coated steel blank comprising a steel substrate with a coating layer
    • heating the blank to a temperature of 800° C or more in a furnace
    • transporting the heated blank from the furnace and placing the blank in a hot forming press
    • hot forming the blank in the press to form the coated steel part
    • quenching the coated steel part

    wherein the heated blank has a temperature of at most 780° C when placed in the hot forming press.
    The invention also relates to a hot formed part manufactured using the method according to the invention.
