[QUOTE="A/C Guy, post: 1952566, member: 13490"] Wiki is wrong, steel requires a more gradual cooling process, literally hours or even days depending upon the specifics. From the link I provided above: [SIZE=6][B]Annealing[/B][/SIZE] Annealing is a process in which a metal is heated to a particular high temperature, held there for a period of between several hours and several days, and allowed to cool. In order for the annealing process to occur correctly, this cooling process must be slow in steels and other ferrous metals. Metals are generally annealed at a temperature slightly above the point at which recrystallization occurs. Special furnaces are used in the annealing process. Conditions in these furnaces are tightly controlled to ensure that the expected changes are taking place. If the steel being annealed is thin and doesn't have adequate thermal mass, then it is place on top of a larger thicker piece of steel heated to almost the same temperature and then placed in an insulated container or vault to cool gradually in shops where a furnace is not conveniently available. Air cooling tempers the steel. Annealing requires more time. Same with brass. Haste makes waste. Don't temper, anneal your brass. [/QUOTE]
