One of the oldest heat treating processes, pack carburizing, is still used because it requires relatively simple and inexpensive equipment and can be used in either batch or continuous type furnaces to produce deep cases which it does efficiently and economically. Parts are surrounded by the pack carburizer, sealed in steel containers and heated in an air furnace to operating temperature.
