H-13

H-13 Air Hardening Tool Steel


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.

TreatmentTemperature RangeCooling/QuenchingNotes
Forging2000-2100° FSlowDo not forge below 1650° F. Anneal after forging.
Annealing1560-1625° FCool 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 Relieving1110-1300° FCool slowly in furnace to 930° F. Then in air.
Preheating1400-1500° FPreheat time in furnace is ¾ Hr. per inch of thickness. Heating up to temperature as slow as possible.
Hardening1830-1900° FTo 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.
