BÖHLER K353

K353 is a universal tool steel for cold working applications, characterized by high hardness, high wear resistance and excellent toughness. K353 is a conventionally produced 8% Cr steel which combines very good machinability, good EDM properties and good dimensional stability.

  • Excellent toughness
  • Very good wear resistance properties: improved adhesive wear resistance thanks to added Al content
  • Hardness up to 62 HRC (high hardness steel)
  • Hardening temperatures in the range of 1030 – 1060 °C (1885 – 1940 °F)
  • Secondary hardening steel with good dimensional stability
  • Well suited to salt bath or plasma nitriding
  • High strength substrate steel for surface coatings
  • Good edge holding ability
  • Easy machinability
  • Good EDM properties
  • Good wire cutting properties
