H-13 is an air hardening, 5% chromium die steel, which is an excellent choice for a wide range of hot work and cold work applications. H-13 is widely used for aluminum, zinc, and magnesium die casting dies where resistance to thermal fatigue due to alternated heating and cooling cycles is of primary importance.
Hot Die steel has excellent toughness and resistance to softening under high temperatures, this steel is used in hot work/warm work forging, die casting, and more recently, in hot stamping molds.

| Treatment | Temperature Range | Cooling/Quenching | Notes |
|---|---|---|---|
| Forging | 2000-2100° F | Slow | Do not forge below 1650° F. Anneal after forging. |
| Annealing | 1560-1625° F | Cool slowly at a rate of 35° F per hour to a 1110° F. | Protect against surface decarburization using controlled atmosphere or by pack-annealing. Hold at temperature for 2 hours. |
| Stress Relieving | 1110-1300° F | Cool slowly in furnace to 930° F. Then in air. | |
| Preheating | 1400-1500° F | Preheat time in furnace is ¾ Hr. per inch of thickness. Heating up to temperature as slow as possible. | |
| Hardening | 1830-1900° F | To minimize distortion, air cool. For maximum hardness diameters greater than 6 should be quenched in oil. | Soak time is 30 minutes per inch of thickness. Minimum of 1 hour. Allow to cool to 125-150° F before tempering |
| Tempering | (See Chart) | In air. | Complete equalization of temperature throughout the tools is essential for good results. Double temper. Recommended temperature is 1000-1200° F. |
