Fdac has the advantages of rapid molding, excellent high temperature strength and wear resistance. The hardness has reached hrc40-44 at the time of delivery. Therefore, it can be directly used in product production without heat treatment. It can greatly reduce the mold processing time. It is mainly used in aluminum, zinc, magnesium alloy die casting die and extrusion die. Also often used in high hard plastic mold (such as the ejector cylinder in the ejection mechanism), such as engine mold.

Chemical composition:

C Si S P Mn Cr V Mo
0.33-0.42 0.80-1.20
0.10-0.15 zero point zero three 0.55-0.75 4.80-5.50 0.30-0.80 1.20-1.60

Heat treatment:

Annealing: heat to 800-850 ℃, stay at this temperature for 2 hours, let it cool gradually in the furnace. Quenching: 550-600 ℃, secondary heating to 850-900 ℃, and then heating to a.1000-1.040 ℃. b. Quenching in oil at 1.040-1.080 ℃ (A. toughness tools are needed; B. hardness tools for hot work) tempering: slow heating to 550-680 ℃, staying at this temperature, and then cooling in still air, tempering should be conducted twice. Hardness: hrc530 ℃.
