H13

Annealed supply condition; final heat treatment is confirmed for the part

Customer materials specify H13 in the annealed condition and state that quenching and tempering are required after machining. They describe balanced high-temperature strength, toughness, thermal-fatigue resistance, and resistance to cracking, molten-aluminum erosion, and aluminum sticking in die-casting service.

• Annealed condition requires heat treatment after machining
• Listed as a general material for aluminum-alloy die casting
