Abstract
A metal customization process that provides an alloy metal product which meets predefined product specifications which are typically based on whole thickness materials. The metal customization process can be used with any commercially available substrates (e.g., aluminum bar, aluminum coil, steel bar, steel coil, and alloys thereof) but, preferably, the substrate is made of steel (e.g., carbon steel, low carbon steel or steel alloys). This process can include receiving a product specification that can include performance or composition criteria; converting the product specification to a surface specification and a core specification; then treating a substrate with a deposition composition, for example, at a temperature below an annealing temperature, thereby depositing at least one alloying element onto the substrate to form a coating composition that is carried by the substrate; and then annealing the coated substrate to provide a product that meets the product specification.
