Low Pressure Surface Treatments 

Low Pressure Carburising (or Vacuum Carburising as it is also known) provides a clean, modern approach to carburising. 

Low Pressure Carburising, or 'LPC', in heat treatment terms, a recent development of vacuum carburising. Many different steels can be successfully treated, even some with relatively poor hardenability. The correct choice of steel will depend on the application and section size being treated.
Benefits over conventional Carburising include: 

  • Lower distortion
  • No intergranular oxidation
  • No decarburization
  • Increased Carbon penetration down fine holes
  • Clean finish
