Annealing is a heat treatment process in which the sheet metal is altered on a molecular level altering its strength and hardness.

What would be the annealling temp.
During the annealing process the metal is heated to a specific temperature where recrystallization can occur.

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.
