Carburising salt melts offer the following advantages:

  • The best temperature uniformity
  • High reproducibility of the carburised surface
  • Easy to control
  • Very flexible to use

Our DUROFER carburising process is environmentally friendly as the products do not contain any cyanide and the carbon activity is controlled by adding the regenerator CECONTROL. This ensures the amount of waste salts are considerably reduced.
