Abstract:
A multilayered composite part includes a plurality of steel alloy layers connected to one another, with at least one core layer consisting of a soft, well deformable steel alloy and at least one steel alloy layer of a very high strength steel alloy, arranged on the core layer. A multilayered composite part which is characterized simultaneously by a high strength paired with very good outer skin quality and very good paint adherence, is achieved in that at least one outer steel alloy layer of a soft, well deformable steel alloy is provided on the very high strength steel alloy layer.
