Ventura Alloy and Steels Supplies and Stocks HCHCR D5 steel in India and abroad. D5 steel is an air hardening, high-carbon, high-chromium tool steel.
APPLICATION
Applications of D5 steels include thread rolling, blanking or forming dies operating at temperatures below 482°C (900°F).
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.
SIZE RANGE
