Uddeholm Ramax HH


Uddeholm Ramax HH is a corrosion resistant holder steel with good machinability, supplied in a high prehardened condition. Good machinability and corrosion resistance reduces tool manufacturing and maintenance costs.

  • Low mould production cost thanks to low wear of the cutting edges in the milling and drilling operations and shorter machining time thanks to increased cutting speeds possible
  • Lower mould maintenance costs due to corrosion resistance
  • Lower production costs since water cooling channels are less effected by corrosion, ensuring consistent cycle time
  • Good machinability
  • Good corrosion resistance
  • Uniform hardness in all dimensions
  • Good indention resistance
