As you’ve gathered by now, if there is no carbon, or there are very low levels of carbon, then virtually no appreciable heat-treatment hardness will be realized. But, if we add carbon to the outer surface of the parts, we can create a case hardness over the core: the core being the inner structure of low carbon material that cannot be heat treated. This process is known as carburization. There are several ways to add this carbon layer to parts that we will look at here, but there are also other ways to treat lower carbon steels and even nonferrous metals, to put a case hardness on them.
