The inside of the oven must be large enough to allow air to circulate around the piece of metal. For large pieces, gas-fired conveyor furnaces are used while car-bottom furnaces are more practical for smaller pieces of metal. During the annealing process, the metal is heated to a specific temperature where recrystallization can occur. Fundamentals of the Heat Treating of Steel ment, and it is not the easiest metal to produce from ore. Copper, for example, exists as nearly pure metal in certain parts of the world. Steel is such an important material because of its tremendousexibility in metal working and heat treating to produce a wide variety of mechan-ical, physical, and chemical properties.
