A2 Tool Steel Heat Treatment Guide A2 tool steel is typically heat-treated by preheating to 1200-1250F (650-675C), austenitizing at 1750-1775F (955-970C), air quenching, and a double-tempering cycle at 400-450F (205-230C). Under controlled conditions, this process produces a stable working hardness of 58-62 HRC with a balanced combination of wear resistance, toughness, and dimensional stability.
