Machining Steel D2

Steel D2 is a Tool Steel (High-alloy steel) that has on top of the 1.5% of carbon an additional 15% of manganese, chromium, nickel, and molybdenum. (See details in the below table). Steel D2 has a machinability rating of 27%.

Steel D2 belongs to the "D series" of tool steels. They are classified as High-carbon, high-chromium, cold-work steels and contain very high Carbon content (up to 2.5%). Tool Steels in this series (D2-D7) have a machinability rating of 20-30%. The high carbon content yields very high hardness and strength resulting in materials that are very difficult to machine

You can find here a list of machinability Ratings for different Tool Steels.

Summery:

  • For turning operations on Steel D2, a lower cutting speed is recommended due to the low machinability. Therefore, in most cases it is recomended to use a grade with high hardness and PVD coating . For milling, opt for a grade with relativly hard substrate.
  • For detailed carbide grades recommendations, check the Below Chart, or use the Grades Wizrad.
  • Recommended Cutting speed range for turning at stable conditions is 330 - 440 [SFM] / 100 - 135 [m/min].
  • Recommended Cutting speed range for milling with stable clamping and short overhang is 200 - 280 [SFM] / 60 - 85 [m/min]
  • For detailed cutting speed recomendations, check the Below Table, or use our Speed and Feed Calculator.
