• Plain Carbon Steels: responsive to quench-and-temper; carbon controls achievable hardness.
• Low-Alloy Steels: add elements (Cr, Mo, V) for hardenability; deeper hardening, improved toughness.
• Stainless Steels: may require solution annealing and specific aging treatments; martensitic, ferritic, and austenitic grades behave differently.
• Tool Steels: often require precise hardening and multi-stage tempering to retain hardness and resist tempering-back.

• Purpose: Reduce residual stresses from forming or welding without significant microstructural transformation.
• Steps: heat below transformation temperatures, hold, then cool slowly.
