Case hardening under protective gas takes place at VTN in multi-purpose chamber furnaces. In this process, the components are first carburized in a controlled protective gas atmosphere with the oxygen being displaced. These components are subsequently quenched in an integrated oil bath. Different quenching oils are used depending on the application. Carbonitriding is a variant of case hardening in which both carbon and nitrogen are deposited onto the surface of the workpiece.
Thanks to state-of-the-art heating and burner technology, we ensure good energy efficiency throughout the entire process.
