Steel Production | History of Western Civilization II
Blister steel used by Huntsman as raw material was made by the cementation process or by carburization of iron. Carburization is a heat treatment process, in which iron or steel absorbs carbon while the metal is heated in the presence of a carbonbearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder.
