METHOD FOR PRODUCING A STEEL COMPONENT WHICH IS SHAPED BY HOT-FORMING A STEEL SHEET WHICH HAS A METAL COATING SUCH A STEEL SHEET AND A STEEL COMPONENT PRODUCED FROM SAID STEEL SHEET BY MEANS OF A HOT-FORMING PROCESS

摘要

The present invention relates to a method for manufacturing a three-dimensionally shaped steel part from a steel sheet having a metal coating and being heated and then formed into a steel part by a hot forming process, -Al-based alloy. To protect the steel sheet or steel part from scale formation, the Fe-Al-based alloy is applied directly onto the steel sheet by a galvanic coating process and / or a physical vapor phase deposition, Or Ti, and / or 0.1 to 10% by weight of Si and / or 0.1 to 10% by weight of Li and / or 0.1 to 10% And / or from 0.1 to 10% by weight Ca, and the alloy has a Fe-Al phase stable above 900 [deg.] C before the heating process of the coated steel sheet to be carried out for the hot forming process. The present invention also relates to a correspondingly coated steel sheet for the production of at least one steel part produced by a hot forming process.
