VTN Witten Herbede

Founded in 1972 as a specialist company for vacuum hardening and nitriding, the company has become the VTN Group’s largest site, with an impressive range of equipment. In addition to the vacuum hardening plant, with one of the largest vacuum furnaces in Europe, the site offers a high-performance nitriding department and a newly built low-pressure carburizing (LPC) department.
In addition, Witten Herbede is one of only a few hardeners in Germany certified according to NADCAP and is therefore approved for the treatment of high-security parts for the aviation industry.

Technologies and processes:

Nitriding furnaces for nitriding and nitrocarburizing as well as VT-N-OX® process
Low pressure carburizing furnaces (LPC) for case hardening and vacuum hardening with oil quenching
High vacuum furnaces for hardening and annealing

High vacuum system for vertical treatment

Induction machines for induction hardening
Pit furnaces for carburizing
