Recrystallization is a thermal process where deformed, strain-hardened grains in a metal are replaced by a new set of defect-free grains. This occurs when a cold-worked alloy is heated above a specific threshold temperature. It restores the metal's ductility and lowers its hardness, allowing for further forming or rolling operations.

We need to run the strip through the annealing furnace to ensure full recrystallization before the next drawing step.
