Our contract hardening plant: Your solution for modern heat treatment
MAN Energy Solutions' hardening plant at the Augsburg site represents long-standing experience and the highest quality in the hardening technology and surface technology sectors, as well as solutions for innovative heat treatment processes.
A major benefit for our customers is that we cover all modern heat treatment processes. From hybrid cleaning and subsequent low-pressure carburizing through to vacuum hardening with high-pressure gas quenching, right up to controlled deep-freezing and gas nitriding. True to our motto of "Everything from a single source", we offer you a complete service around the clock and take responsibility for developing a solution even in complicated cases. Our experts would be happy to help you with any questions you may have regarding our innovative heat treatment processes.
Latest hardening plant technology and long-lasting service
The hardening plant was completely renovated between 2016 and 2018 and now boasts the latest heat treatment technologies for use in various heat treatment processes.
The modern plant makes it possible to produce oxidation-free surfaces, eliminates retained austenite and enables uniform low-pressure carburizing.
Alongside the process optimization, these new developments also play a role in sustainably maximizing the service life of components.
Our contract hardening plant is available to all customers from the hardening technology, surface technology and material analysis sectors.

Processes
As a full-service company, we are able to offer complete heat treatment processes from a single source.
1. Cleaning
Hybrid cleaning is an alkaline/alcoholic ultrasonic cleaning process with maximum cleaning power. Three cleaning methods are possible: Swivel cleaning, spray cleaning and air purification.
Other benefits:
- Vacuum drying of components after cleaning
- Regular concentration measurements of the cleaning medium in our internal chemistry department
2. Carburizing
In contrast to conventional carburizing, low-pressure pulsed carburizing prevents surface oxidation which would go on to cause component failure. This new technology therefore extends the service life of components.
Other benefits:
- The carbon transfer rate is very high
- Extremely uniform carburizing even with complex geometries
- Excellent cost-effectiveness thanks to minimal gas consumption
- Short process times thanks to high carburizing temperatures
3. Hardening
Vacuum hardening with high-pressure gas quenching takes place at a nitrogen pressure of up to 20 bar and prevents surface oxidation.
Other benefits:
- Single-chamber furnace with reversing cooling
- Two-chamber furnace with cold chamber
4. Deep-freezening
The deep-freeze furnace is able to cover a temperature range from -120 °C to 600 °C. This makes deep-freezing with subsequent tempering possible without needing to change furnace.
Other benefits:
- The deep-freezing process minimizes the retained austenite content in the component
- No corrosion on the components
5. Nitriding
Gas nitriding with nitriding potential control is adapted to the furnace load.
Other benefits:
- The furnace systems have an oxygen probe to precisely monitor the pre-oxidation and post-oxidation processes
- External rapid cooling at the furnace systems speeds up the cooling process and reduces the process times
- Controlled gas nitrocarburizing is possible
We can offer everything from one source, from a hybrid cleaning plant to a deep-freeze furnace.
Your benefits
