==PLATED STEEL SHEET FOR HOT STAMPING AND HOT-STAMPED MEMBER - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17768161 titled 'PLATED STEEL SHEET FOR HOT STAMPING AND HOT-STAMPED MEMBER

==Simplified Explanation==

The plated steel sheet for hot stamping described in the abstract has a steel sheet with a plating layer containing at least 60% Al and a surface film layer. The plating layer is 10 to 60 μm thick, with an average crystal grain diameter of 15.0 μm or less. The surface film layer contains particles of elements like Sc, V, Mn, Fe, Co, Ce, Nb, Mo, and W, with a total content of 0.01 to 10.0 g/m. The average grain diameter of these particles is 0.05 to 3.0 μm.

* Steel sheet with plating layer containing 60% Al or more
* Plating layer thickness of 10 to 60 μm
* Surface film layer with particles of selected elements
* Average grain diameter of particles in surface film layer is 0.05 to 3.0 μm

==Original Abstract Submitted==

A plated steel sheet for hot stamping according to one aspect of the present invention includes a steel sheet, a plating layer formed on either surface or both surfaces of the steel sheet and having an Al content of 60 mass % or more, and a surface film layer formed on the plating layer. A thickness t of the plating layer is 10 to 60 μm. An average crystal grain diameter of the plating layer in a thickness range from an interface between the plating layer and the surface film layer to a position at ⅔ of the thickness t is 2t/3 or less and 15.0 μm or less. A surface film layer contains particles containing one or more elements selected from A group elements consisting of Sc, V, Mn, Fe, Co, Ce, Nb, Mo, and W. A total content of the A group elements is 0.01 to 10.0 g/m. An average grain diameter of the particles containing the A group elements is 0.05 to 3.0 μm.
