Carburizing granulate
- Workpieces are placed into an annealing box with carburizing powder or granulate and the lid is closed and sealed
- At approx. 900 °C the steel reacts with the carbon and forms an approx. 0.2-2 mm thick layer
- The thickness of the layer depends on the length of the process, approx. 0.1 mm/hr, a process time of approx. 6-8 hrs achieves good average results
- Powder for alloyed and non-alloyed steels for single use as well as granulate for multiple use with approx. 20 % new granulate added
- Supplied in 25 kg sacks
