Method for the production of thin-walled steel components and components produced therefrom

A part made from steel wherein said part is made from a plurality of different steel layers cast together, said part comprising:

• a cold rolled multilayer composite material comprising:
• a) at least one surface layer which has been changed with regard to strength or hardness quality;
• and
• b) at least one core layer which has not been changed in strength or hardness quality
• wherein the composite material formed from said plurality of different steel layers is formed by connecting said at least one core layer and said at least one surface layer together wherein at least one 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 said at least one core layer and said at least one surface layer;
• wherein the composite material is deformed along a length of said layers;
• and
• wherein said layers are heat treated to transform said strength and hardness qualities of at least one of said surface layers.
