Hot Stamp Formed Article
Abstract: This hot-stamp formed article comprises a steel sheet. The steel sheet has a prescribed chemical composition. In the steel sheet, the average B-concentration in a region between a depth of 5.0 µm from the surface and a depth of 25.0 µm from the surface is at most 0.700 times the B-concentration in a position at a depth of 100 µm from the surface. The average B-concentration in a region between a depth of 0.5 µm from the surface and a depth of 4.0 µm from the surface is at least 1.600 times the B-concentration in a position at a depth of 100 µm from the surface. The average O-concentration in said region between a depth of 0.5 µm from the surface and a depth of 4.0 µm from the surface is more than 0.0150 mass%.
