Uddeholm Chipper


Uddeholm Chipper is a versatile, high alloyed tool steel characterized by the excellent combination of toughness and wear resistance required for chipper-knives and heavy duty blanking and forming.

  • Short lead times in tool making
  • Right combination of toughness and wear resistance for heavy duty blanking and forming
  • Ideal for surface coating (PVD, CVD)
  • Good dimensional stability during heat treatment
  • Good machinability and grindability
  • Excellent combination of toughness and wear resistance
  • Normal hardness in the range 52 – 58 HRC
