Abstract
Disclosed is a hot-stamping component, which includes a base steel plate; and a plated layer on the base steel plate and including a first layer, a second layer, and an intermetallic compound portion having an island shape in the second layer, wherein the first layer and the second layer are sequentially stacked, and an area fraction of the intermetallic compound portion with respect to the second layer is an amount of 20% to 60%.
Claims5
A method of manufacturing a hot-stamping component, the method comprising:
- manufacturing a plated steel plate by immersing a base steel plate in a plating bath comprising aluminum and silicon;
- coating the plated steel plate with an oil comprising an ester-based compound;
- forming a blank by cutting the plated steel plate coated with the oil;
- and
- heating the blank in a heating furnace,
- wherein the oil comprises an amount of 10 wt % to 30 wt % of hydrotreated heavy paraffin refined oil, an amount of 30 wt % to 50 wt % of solvent-dewaxed heavy paraffin refined oil, an amount of 1 wt % to 5 wt % of solvent-refined heavy paraffin refined oil, and an amount of 10 wt % to 40 wt % of an ester-based compound.
