Abstract

The invention relates to a method for producing a metal component, wherein a raw material (4, 34, 42, 74) is provided, the raw material (4, 34, 42, 74) is stamped and is further processed following the stamping process to form a component (90, 108, 114). The component (90, 108, 114) has at least partially stamped areas (16, 36, 48, 98), and the raw material (4, 34, 42, 74) is hot-stamped. The invention further relates to the use of a hot-stamped metal component, which is preferably produced using a method according to the invention, in a motor vehicle body, in particular as a reinforcing element in a B-column (114), a sill, or a longitudinal beam.
