Tempering alters the crystal structure of the alloy. The effect produced depends on the composition of the alloy, the temperature to which it is heated, and the rate at which it is cooled. Usually, the metal is heated slowly to a specific temperature, then cooled rapidly. Tool steel is hardened in this way.
