Beschreibung
Zusammenfassung:	The invention relates to a hot-forming material composed of a three-layer composite material, comprising a core layer of a hardenable steel which in the press-hardened state of the hot-forming material has a tensile strength >1900 MPa and/or a hardness >575 HV10, more particularly a tensile strength >2000 MPa and/or a hardness >600 HV10, preferably a tensile strength >2100 MPa and/or a hardness >630 HV10, more preferably a tensile strength >2200 MPa and/or a hardness >660 HV10, more preferably still a tensile strength >2300 MPa and/or a hardness >685 HV10, and two outer layers bonded substance-to-substance with the core layer and composed of a steel which is softer in comparison with the core layer and which in the press-hardened state of the hot-forming material have a tensile strength >750 MPa and/or a hardness >235 HV10, more particularly a tensile strength >900 MPa and/or a hardness >280 HV10, preferably a tensile strength >1000 MPa and/or a hardness >310 HV10, more preferably a tensile strength >1100 MPa and/or a hardness >340 HV10, more preferably still a tensile strength >1200 MPa and/or a hardness >370 HV10. The invention further relates to a component and also to a corresponding use.
