Protective gases for the annealing of ferrous and non-ferrous metals

For almost all annealing processes, we offer inert gas atmospheres based on inert nitrogen in combination with controlled amounts of hydrogen, methanol or hydrocarbons.

Perfect surfaces and reduced reworking – with our protective gas atmosphere

Flexible protective gas atmosphere for carburizing and neutral hardening

Nitrogen, methanol and a small amount of a hydrocarbon gas are mixed in the furnace to a reaction atmosphere which corresponds essentially to that of an endogene during carburizing, carbonitriding and hardening.

Numerous advantages over endogas

For neutral Hardening in some cases a N2/ Hydrocarbon blend could be used to reduce operation cost and toxic flamable components.
