Process for the deep drawing of metal sheets, characterized by the fact of subjecting sheets of high alloy steel, to a central compression that tends to force them into a mold cavity, simultaneously with the application of a laminating effect on the areas of sheet metal that surround the drawing area, being the conditions of this process controlled, in relation to the progress of the drawing, so that the embossed piece presents a uniform thickness along a generatrix, from the center of its bottom to the zone of confluence of the same with the lateral walls, where a transition to a smaller thickness takes place, continuing constant with this reduced value until the edge of the container.
