5. Heat Treatment |
H13 tool steels are preheated to 816°C (1500°F). Then the steels are directly heated by increasing the temperature to 1010°C (1850°F) followed by holding for 15 to 40 mins. The steels are then air-quenched.

7. Forging |
H13 tool steels are forged at 1079°C (1975°F). For this type of steels, forging below 898°C (1650°F) is not preferable. | ||||||||||||||||||||||||||||||||||||
8. Annealing |
H13 tool steels are annealed at 871°C (1600°F) and slowly cooled at 4°C (40°F) in the furnace. | ||||||||||||||||||||||||||||||||||||
9. Tempering
10. Stress Relieving |
Tempering is carried out in H13 tool steels from 538 to 649°C (1000 to 1200°F) to obtain Rockwell C hardness of 53 to 38. Double tempering can also be performed in these steels for every one hour at the preferred tempering temperature. | ||||||||||||||||||||||||||||||||||||
When tools made from H13 tool steel are heavily machined or ground , the relief of internal strains is advisable before hardening to minimise the possibility of distortion. Stress relieving should be done after rough machining. To stress relieve, heat the component carefully to 700°C, allow a good soaking period (two hours per 25mm of ruling section). Cool in the furnace or in air. The tools may then be finish machined before hardening.

10. Highlight advantage: | high hot strength and hardness --good resistence to heat, good hot toughness, high resistance to temperature fatigue and wear in medium heat --small heat deformation --the tendency of the appearing of iron oxide skin are small in air-quenching --excellent corrosion resistance | ||||||||||||||||||||||||||||||||||||
