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 invention relates to a method for producing a three-dimensionally shaped steel component from a steel sheet which has a metal coating and which is heated and subsequently shaped into the steel component by means of a hot-forming process. The steel sheet used has an Fe-Al-based alloy as a metal coating. In order to protect the steel sheet or the steel component from scaling, an Fe-Al-based alloy is applied directly onto the steel sheet by means of a galvanic coating process and/or a physical vapor phase deposition, wherein the coating produced in this manner contains 30 - 60 wt.% Fe, a group of Al, and optionally 0.1 - 10 wt.% Mg and/or 0.1 - 5 wt.% Ti and/or 0.1 - 10 wt.% Si and/or 0.1 - 10 wt.% Li and/or 0.1 - 10 wt.% Ca, and the alloy has an Fe-Al phase which is stable up to over 900 °C prior to the heating process to be carried out for the hot-forming process. The invention further relates to a correspondingly coated steel sheet for producing one or more steel components produced by means of a hot-forming process.
