Premium H-13 NADCA Class B

Our hot work die steel, DAC-P is most widely used as die insert material for aluminum and zinc die casting molds. With the introduction of isotropic technology, DAC-P material has become tougher with improved stability for prolonged die life. Although DAC-P material was modified from H13 grade steel, DAC-P has improved the balance of strength, toughness and heat resistance.  Read more below or inquire with the DTS team to discover which of your processes can be improved with a premium H13.


DAC-P meets the material specification of NADCA #207.  In addition, DAC-P was recently listed as provisional insert material on GM DC-9999-1 and Ford AMTD-DC2010 standards documents.


  • Good balance of both strength at elevated temperature and toughness
  • Good machinability with less deformation after heat treatment


  • General die for aluminum die casting
  • Die for zinc die casting
  • Low-pressure wheel casting
  • Forging and Extrusion

DAC-P Premium H13 can be produced in large cross section on Hitachi’s production facility in Yasugi, Japan using newly installed 10,000MT hydraulic open die press with twin-manipulators. This technology allows a higher ratio of forging reduction and strongly enhances impact toughness values as measured in the Charpy impact test.
