Die Steel

D2 tool steels are utilised for long run tooling applications where wear resistance is crucial, such as blanking or shaping dies and thread rolling dies, in the automotive, construction, pharmaceutical / chemical, and oil & gas industries.

Highcarbon, highchromium steels, or group D steels, are examples of coldwork tool steels. These steels are classified as group D steels and include D2, D3, D4, D5, and D7. These steels have a carbon content of 1.5 to 2.35 percent and a chromium content of 12 percent. Except for type D3steel, all other group D steels are air hardened and contain 1% Mo. Oil quenching is used for Type D3 steel, while small parts can be gas quenched after austenitization with vacuum.
