DH31-EX
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.
