57 Abstract AB [EN] A process for the production of thin walled parts of steel, wherein there are layers that are at least partly differently treatable relating to their strength and hardness qualities. This process can include creating a composite material from a plurality of different layers by connecting at least one core layer and at least one surface layer together. At least one layer of the core or surface layer is cast adjacent to another layer to form a composite material having an alloy gradient that is flat at each interface between any of the core layer or the surface layer. Next, the process can include deforming the composite material along a length of these layers. Finally the process can include heat treating the layers to transform the strength and hardness qualities of at least one of these layers.
