Fabrication and Heat Treatment
Heat Treatment
D5 steels should be preheated very slowly up to 815°C (1500°F), then temperature should be increased to 1009°C (1850°F) and held for 20 to 45 minutes. Then they are air quenched.
Forging
Forging of D5 steels can be done at 1065°C (1950°F) down to 1750°F. Do not forge below 926°C (1700°F).
Annealing
Annealing of D5 steels should be done at 886°C (1627°F) followed by slow furnace cooling at 4°C (40°F) per hour or less.
Tempering
D5 steels can be tempered at 204°C (400°F) for achieving Rockwell C hardness of 61 and at 537°C (1000°F) for a Rockwell C hardness of 54.
Applications
Applications of D5 steels include thread rolling, blanking or forming dies operating at temperatures below 482°C (900°F).
