Hi Jim! Good seeing you on here.

Heat Treated and Annealed. Annealing is a specific process, which follows Heat Treatment for mechanical properties. That term is no longer used in that context, replaced by 'Stress Relieved', though the term is still used signifying a 'draw' cycle, meaning to 'soften'.
