Introduction:
Cold-work tool steels include the high-carbon, high-chromium steels or group D steels. These steels are designated as group D steels and consist of D2, D3, D4, D5, and D7 steels. All group D steels include 1% Mo and are air hardened except for type D3 steel. Type D3 steel is oil-quenched; though small sections can be gas quenched after austenitization using vacuum. Consequently, tools made with type D3 steel tend to be brittle during hardening. Type D2 steel is the most commonly used steel among the group D steels.
The following section will discuss more about D4 type of tool steels.
