Abstract

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 DEG 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.

Description

technical field [0001] The invention relates to a method for producing a three-dimensional shaped steel component from a steel sheet with a metal coating, which is heated and subsequently formed into a steel component by hot forming, wherein the steel sheet used comprises Fe as metal coating - Al-based alloys. Furthermore, the invention relates to a steel sheet for the production of one or more steel components produced by hot forming, which is provided with a metallic coating consisting of an Fe-Al-based alloy. Furthermore, the invention relates to a formed steel component produced by hot forming such a steel sheet. Background technique [0002] In the case where steel is heated to about 500° C. or higher in an atmosphere containing oxygen, an oxide layer, ie, a so-called scale, is formed on the steel surface. Scale formation is generally undesirable as scale poses serious problems. The penetration of scale during the forming of the steel sheet can thus lead to surface m...
