Boronizing, also known as “Boriding”, is a case hardening process where boron atoms are diffused into the surface of a metal component. Boronized metal parts are extremely wear resistant and will often last two to five times longer than components treated with conventional heat treatments such as hardening, carburizing, nitriding, nitrocarburizing or induction hardening.

Properties of Boronizing

  • Extremely high wear resistance
  • High hardness (1300-2000HV is possible)
  • Resistance to high temperatures with no adverse effects up to 1200F temperature
  • Increased corrosion resistance to acids
  • Reduced coefficient of friction
  • Increased galling / cold-welding resistance
  • Wide range of materials possible for treatment

Applications of Boronizing

  • Plain carbon steels
  • Alloy steels
  • Tool steels
  • Nickel-based super alloys
  • Cobalt alloys
  • Stellite
  • Possible to combine with other heat treatments such as carburizing, hardening or induction hardening to create deeper wear layers or high core hardness.
  • Can be selectively applied
