Ferritic Nitrocarburizing in Salt Baths -Tenifer®
The best alternative to the gas nitriding is the ferritic nitrocarburizing made in salts baths with traditional process Tenifer® by Degussa.
Salt Baths: Martempering, Austempering, Carburizing, Carbonitriding, Quenching of HS, HSS and tool steels
Why to use still in the 2000’s the “old” technology of salts baths to make massive heat treatments of steels and speed steels?
Carburizing, Carbonitriding, Quenching and Tempering and Hardening of small and very small pieces
The use of endothermic atmospheres in continuous furnaces is the best technology to guarantee the achievement of the carburizing and carbonitriding depth almost identical on all the
Controlled Atmospheres: Carburizing, Carbonitriding, Quenching and Tempering, Annealings and Normalizing
The execution of the massive heat or thermochemical treatments in furnaces at regulated endothermic atmosphere (O2 probe) “sealed quench ”type is, actually, the best way to manage economically the industrial production balancing this way the ratio cost/result.
Vacuum Heat Treatments
HS, Tool Steels, stainless steel, PH, Maraging, Ni and Co Superalloys..
The use of vacuum technologies with pressure gas quenching joined to control and management systems of parameters of heat treatment by software allows to ensure to the growing
Gas nitriding
The main advantages of nitriding originate from the parameters themselves of the thermochemical treatment, very different from those of the carburizing, and varies from the lack of deformations (or their reduction to a minimum) to a veryrestricted increasing in volume respect to volume changes (often out of control) reached with carburizing, allowing in many cases the elimination of finishing operations. The technological advantages come from an average higher surface hardness of the nitrided layer with consequent raising of the wear and erosion resistance and an increasing in mechanical fatigue resistance; in addition, that hardness is maintained up to high exercise temperatures (advantage particularly interesting in the field of tools which work at temperatures higher than 150 ÷ 200 ° C and subjected to thermal fatigue).
The use of the H2 probes to check the nitriding potential (KN) in the atmosphere allows to manage the process gases and, consequently, the making of nitride in function of the customers need.
The wide range of our nitriding devices allows a high flexibility, a very important factor to be your punctual and reliable partner.
