Properties

D-2 is typically bought to meet chemistry requirements rather than physical requirements. For that reason, physical properties are generally not provided unless requested prior to production. Any material can be sent to a third party after production to be tested for physical properties.

Typical Uses

D2 tool steel can be used to create a variety of parts. Typical applications include:

  • Blanking Dies
  • Forming Dies
  • Coining Dies
  • Slitting Cutters
  • Heading Tools
  • Long Punches
  • Forming Rolls
  • Edging Rolls
  • Master Tools
  • Drawing Dies
  • Shear Blades
  • Gauges

What is D2 Drill Rod?

D2 Drill Rod is D2 Tool Steel round stock that has been ground to a very tight tolerance. Buying this ground rod lets you get straight to making your part(s) because no up front preparation is required. In addition to grade D-2, drill rod is available in other grades (see below). D2 is air-hardened and has a higher alloy content which makes it the toughest of the drill rod grades.

More About D-2 Tool Steel

D-2 is a very deep hardening steel and will be practically free from size change after proper treatment. The high percentage of chromium gives it mild corrosion-resisting properties in the hardened condition. It has low machinability and grindability, with a medium resistance to decarburization.

If you need something other than a round drill rod, consider Alro's Super Square. Alro can precision mill D2 Tool Steel into a Super Square - these can be 2, 4, or 6 side precision milled pieces. Alro will precision mill to customer tolerances and do it fast. For other shapes, Alro Steel is also able to grind tool steel with a rotary grinding machine for a fast turnaround, with reciprocal grinding for an even smoother finish. Alro Steel is a large tool steel supplier offering a wide variety of tool steels suitable for various applications.
