Document Type and Number:
WIPO Patent Application WO/2023/234508
Kind Code:
A1
Abstract:
The present invention relates to a hot stamping component, and provides a hot stamping component comprising: a base metal; a decarburization layer arranged on the base metal; and an internal oxide layer arranged on the decarburization layer, wherein the hot stamping component has a tensile strength (TS) of 1,350-1,680 MPa, and the hardness within 50 μm depth from the surface of the hot stamping component in the sheet thickness direction of the hot stamping component and the average hardness of the hot stamping component satisfy the following relation 1. (A/B) ≤ 0.7 (In relation 1, A is the hardness (Hv(≤50 μm)) within 50 μm depth in the sheet thickness direction of the hot stamping component, and B is the average hardness (Hv(avg.)) of the hot stamping component.)
