International Mold Steel DH2F Pre-Hardened H13-Type Mold Steel
Categories: Metal; Ferrous Metal; Tool Steel; Hot Work Steel; Mold Steel

Material Notes: Description: DH2F is one of the best machining pre-hardened H13-type steels available.

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.

Applications:

  • Molds for plastics
  • Diecast die components
  • Plunger tips, sprue bushings
  • Diecasting dies for aluminum and zinc
  • Dies for aluminum extrusions
  • Press dies
  • Dieplate strippers
  • Machine parts
