Details

*** Suggested for high speed pressing and over 700°C under continuous-press.

Our steels can be supplied:

  • In bars.
  • In cut-to-size pieces according to customers’ requests  and pre-bored.
  • In module for dies machined under extremely close tolerances, ready to machine the figure.
  • In finished toolings, such as pins, inserts, matrices machined under customer’ s specific technical drawing.  
DELIVERY CONDITIONS
   ¤ Annealed to a maximal hardness of 300 HB
 
Hot work tool steel , alloyed with Cr, W, Mo, and Co. For tools subject to critical stresses in hot- stamping, without cooling during server at high temperature requiring hot flow. The steel has high tempering resistance to maintain his strength at the high to service temperatures.
¤ High thermal shock resistance and thermal fatigue
¤ Good toughness and ductility
¤ Good machining
¤ Good dimensional stability during the thermal treatment
¤ High tempering stability in service
 
PRODUCT APPLICATIONS
¤ Toolings for stamping under press of non ferrous materials.
¤ Inserts for die-casting moulds (heavy alloys)
¤ Toolings for heavy metals extrusion (matrices, punches, spindles,etc.)
  
RECOMMENDATIONS FOR A BEST LIFE OF TOOL
Pre-Heat the tool slowly in order to homogenize the temperature in surface and in the core between 250 and 300°C.
