Metal-hardening technology in our in-house hardening facilities
Berger metal-hardening technology has been well-known worldwide since 1985, because Precision in perfection is also a vital matter for us in the field of heat treatment. With our own in-house hardening facilities at the locations in Memmingen and Poland we are a leading service provider internationally for customer-specific forms of heat treatment, and in the meantime we have become a partner for a great many leading companies including, among others, ones from the automotive sector and machine construction. We not only harden parts that we have produced ourselves, but also provide a service for other companies as a contractor.
Currently we have free capacity available.
Our expertise in metal-hardening technology
Here we process case-hardened steels, tempered steels, roller bearing steel, spring steel, tool steels, non-rusting steels, aluminum alloys, etc.
Depending on the customer requirements, the batching can be done as individual items, small batches or in bulk.
Chamber furnace line
Production procedures under a conventional inert gas atmosphere with oil quenching
- Single and direct hardening
- Quenching and tempering
- Various forms of annealing
Vacuum furnace line
Production procedures with N2 high-pressure gas quenching up to 20 bar
- Vacuum direct hardening
- Low-pressure carburizing
- Various forms of quenching and tempering
- Vacuum case-hardening
- Gas nitriding and nitrocarburizing
Additional procedures for heat treatment
- Inductive hardening
- Inductive tempering
Hardening also includes quality assurance. After the hardening process the parts are tested using the requisite procedures according to the details given in the test plan. We carry out Vickers, Rockwell and Brinell tests. The fully automatic hardness tester can test up to six samples at the same time, with the test results being electronically recorded, documented and archived.
All the processes are carried out with due regard for the strictest current certification requirements:
- ISO 9001:2015 / IATF 16949:2016 (Quality)
- ISO 14001:2015 (Environment)
- ISO 50001:2011 (Energy)
