Abstract: The present invention provides a hot stamping component having a tensile strength of 1350 Mpa or greater, including a microstructure including prior austenite grains (PAG), wherein an average particle diameter of the PAGs is 35 ?m or less.

Abstract: A method of manufacturing a hot stamping includes: inserting a blank having a plating layer formed on at least one surface of a base material into a heating furnace having a plurality of sections having different temperature increase rate ranges; and multi-stage heating the blank gradually while passing through the plurality of sections. The plurality of sections include: a first heating section having a first average temperature increase rate change rate; a second heating section having a second average temperature increase rate change rate different from the first average temperature increase rate change rate; and a third heating section having a third average temperature increase rate change rate different from the first average temperature increase rate change rate and the second average temperature increase rate change rate. The third average temperature increase rate change rate includes a section in which a positive value is changed to a negative value.

Abstract: Disclosed herein is a method and apparatus for manufacturing a panel for a vehicle. When a steel sheet is machined to form a panel for a vehicle, a blanking-texturing machine conducts a blanking process for cutting the steel sheet and a texturing process for forming depressions in the steel sheet at the same time. Therefore, the present invention reduces the number of manufacturing processes, thus enhancing the productivity, and reducing the production cost and provides a steel sheet with uniform depressions across the surface of the steel sheet, thereby reducing the coefficient of friction during the pressing process consistently.
