Abstract:
A composite steel plate in which at least two steel sheets are rolled to form a plate. One of the sheets has a composition that varies in a depthwise direction between nanocrystalline and micron grained. The plate is made by treating a steel sheet to produce a composition in the sheet that varies in a depthwise direction of the sheet between nanocrystalline and micron grained, stacking the treated sheet with at least one other steel sheet and rolling the sheets to form the plate.
