Title: FLAT STEEL SEMI-FINISHED PRODUCT, METHOD FOR PRODUCING A COMPONENT, AND USE THEREOF
Abstract:
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 > 370 HV10, 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.
