Download ExELL™ FORGEDIE Spec sheet

ExELL™ ForgeDie is a chromium-nickel-molybdenum alloy hot-work steel which has been developed especially for forging die block applications. ExELL™ ForgeDie is characterized by:

  • Good through hardening characteristics resulting in good hardness distribution even in very large sections
  • Excellent machinability
  • Good hot strength and hot hardness
  • Easy repair welding

ExELL™ ForgeDie is manufactured in a fully integrated manufacturing facility for specialty tool steels. The facilities are state-of-the-art beginning with advanced ASEA-SKF steel making capabilities that include an ultra high power electric arc furnace with subsequent/multiple ladle refining, and vacuum degassing for the most complete and modern ladle metallurgy technology. New high powered open die forging presses, heat treat and machining equipment complete the die steel manufacture in ISO 9001 facilities.
