Method to produce a hot formed part, and part thus formed

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.
