Abstract
A press-hardened shaped metal sheet has at least two adjacent zones having different sheet thicknesses and different strengths such that one of the zones is press-hardened and the other zone is non-hardened or only slightly hardened. A transition zone, which is simultaneously designed as a thickness transition zone and as a strength transition zone, is located between the zones. The press-hardened shaped metal sheet is preferably a pillar reinforcement for a motor vehicle body.
