A Quick Guide to Annealing: What is Annealed Metal?
Annealing removes what's called residual stress. Residual stress is what remains in a metal after the original cause of the stress has been removed. For example, residual stress from roll forming could cause a structural to gape when cut with a band-saw. Residual stress can complicate future processes and annealing is a great way to remove it.
