Casehardening Case"hard`en*ing, n. The act or process of converting the surface of iron into steel. --Ure. [1913 Webster]

Note: Casehardening is now commonly effected by cementation with charcoal or other carbonizing material, the depth and degree of hardening (carbonization) depending on the time during which the iron is exposed to the heat. See {Cementation}. [1913 Webster]
