Beschreibung
Zusammenfassung:	The invention relates to a flat steel semi-finished product (1), comprising a first layer (1.1) made of a martensitic steel alloy, which has a tensile strength of > 1200 MPa and/or a hardness of > 370HV10, and at least one second layer (1.2, 1.2') made of a soft steel alloy, which is connected to the first layer (1.1) over the full surface area and in a material-to-material manner, having a tensile strength of < 600 MPa and/or a hardness of < 190 HV10. The invention further relates to a method for producing a component from the flat steel semi-finished product, and to a corresponding use. 本发明涉及一种扁钢半成品(1)，其包括马氏体钢合金组成的第一层(1.1)，其抗拉强度＞1200MPa和/或硬度＞370HV10，和至少一个与第一层(1.1)全面地且材料配合连接的、由软钢合金组成的第二层(1.2,1.2')，其抗拉强度＜600MPa和/或硬度＜190HV10。本发明还涉及由该扁钢半成品生产组件的方法和相应的应用。
