Metallurgical coal (also called "met" coal) is an important raw material used in the steelmaking process, although very small amounts of coal (relative to the amount used for electricity) are needed. The coal used to make steel is heated without air in an oven at temperatures of as much as 2,060°F (1,125°F), until most of its volatile matter is released.
