Applications

Built For High-Wear Cold Work Tooling

  • Dies
  • Punches
  • Blanking Tools
  • Forming Dies
  • Industrial Blades
  • Embossing & Coining Dies

  • Plastic & Rubber Processing Tools

D-3 is particularly suited to low-impact, high-abrasion applications where wear resistance and edge retention are priorities.

Heat Treatment

Heat Treatment

Engineered For High Hardness & Wear Resistance

D-3 is heat treated to develop the high hardness, wear resistance and dimensional stability required for demanding cold-work tooling applications.

Hardening

D-3 undergoes controlled hardening to achieve the required tooling hardness.

Tempering

Tempering is carried out after hardening to balance hardness, toughness and dimensional stability according to the application.

Final Hardness

D-3 can achieve approximately HRC 60–62 after proper hardening, as stated in the supplied reference.
