Carburizing And Carbonitriding

carborizing

Carburizing and carbonitriding salt melts feature following advantages:

best temperature uniformity
high reproducibility of the carburizing effect
easy to control
very flexible in use

The DUROFER® process is an environmental friendly process as the products do not contain any cyanide. The carbon activity is controlled by adding the regenerator CECONTROL®. Hence the amount of waste salt is considerably reduced. This technology can also be used for hardening being free of decarburization as long as the melt is set for low activity.

DUROFER® Process

Product	Application	Working temp. in °C
CECONTROL®	Regenerator; for use only with the base salts CECONTROL® 50 H, 80 B und 110 B
CECONTROL® 50 H	Cyanide-free starter and replenishment salt to achieve a surface carbon level of approx. 0.5 % C; for use only with CECONTROL® regenerator	780 – 950
CECONTROL® 80 B ------------------------ CECONTROL® 110 B	Cyanide-free starter and replenishment salt to achieve a surface carbon level of approx. 0.8 resp. 1.1% C; for use only with CECONTROL® regenerator	820 – 950
