International Mold Steel

DHA-World

DHA-World is a high hardenability and high tough general use hot work die steel.

Overview  

Improved H13 applicable for a wide variety of uses High toughness even in large dies due to higher hardenability than that of H13

Applications include:

Die Casting Molds

Die Casting Parts

Hot Extrusion Dies

Hot Shear Blades

Hot Forging Dies

Unique Characteristics

  • 38-42 HRc hardness.
  • Through hardened for exceptional dimensional stability.
  • Cuts mold making costs by reducing man hours required for machining.
  • Classified as a “free-machining” steel.
  • Ideal for complex, precision molds and parts susceptible to distortion and/or deformation without needing additional heat-treating.
  • Ideal for Ion-nitriding.
