Technologies

Hauck Heat Treatment operates processing facilities in strategic locations around Europe, enabling us to offer all types of heat treatment processes. Our facilities are closely interlinked in terms of logistics, which means that all processes are available to you even if the specific process you seek is not available at the nearest Hauck Heat Treatment location.

At Hauck Heat Treatment we have divided our processes into five core technologies, which are listed below. Selecting a process leads to a description.

The technologies we offer in our group companies in the Netherlands are listed below. For a complete list of technologies we offer as Hauck Heat Treatment group, please check our general website: www.hauckht.com.

Thermal Processes

Technology

Hardening & Tempering

Thermal processes are all Heat Treatment processes which only involve heating of the products to be treated. With these processes we are able to optimize the mechanical properties of the products.

Vacuum Hardening & Tempering
Atmospheric Hardening & Tempering
Precipitation / Age Hardening
Aluminium Heat Treatments

Technology

Sub-Zero Treatments

Sub-Zero Treatments are processes where the products are treated at a temperature below zero degrees Celcius. The treatment can be an additional step in the hardening process to reach optimal results in hardness and structure of the material or can be part of an aging process.

Technology

Annealing

Annealing processes serve to influence the structure of the material or to reduce internal tensions. These processes are done at temperatures up to approximately 1150°C.

Technology

Carburizing

Carbureren is een van de thermochemische processen. Tijdens dit proces is de rand van werkstukken verrijkt met koolstof om de mechanische eigenschappen van de randlaag van het werkstuk te verbeteren. Het verharden van de behuizing bestaat meestal uit drie stappen. In de eerste stap worden werkstukken blootgesteld aan een koolstof-emitterende omgeving. Dit verhoogt het koolstofpercentage aan de rand van het werkstuk.

Het koolstofprofiel en de penetratiediepte zijn afhankelijk van de tijd op temperatuur, de hoeveelheid toegevoerde koolstof, de temperatuur en het soort staal dat wordt gebruikt.

In de tweede fase vindt afschrikking (verharding) plaats. Dit kan direct worden uitgevoerd vanaf de cementeringstemperatuur, of na een tussentijdse koeling of nieuwe verwarming tot een nieuwe materiaalspecifieke uithardingstemperatuur.

De derde stap is ontlaten en dient voornamelijk om de hoogste spanningen in de structuur te verminderen en om de scheurgevoeligheid te verminderen.

Technology

Carbonitriding

Carbonitriding is one of the thermochemical processes. During this process the edge of workpieces is enriched with carbon and Nitrogen to improve the mechanical properties of the edge layer of the workpiece. Carbonitriding – similar to carburizing Carburizing – typically consists of three steps. Read more for the full description.

Technology

Nitriding

Nitriding belongs to the thermochemical processes. During this processes the surface of several workpieces or machine parts is enriched with nitrogen to improve the mechanic properties of the surface of the workpieces or machine parts.

Technology

Nitrocarburizing

Nitrocarburizing belongs to the thermochemical processes. During this processes the surface of several workpieces or machine parts is enriched with nitrogen and carbon to improve the mechanic properties of the surface of the workpieces or machine parts.

Technology

Nitrotec®

Nitrotec® is a worldwide trademarked surface engineering process for the treatment of steels and cast irons carried out in the temperature range of 590 -740°C using a gaseous nitrogen bearing atmosphere.

Technology

Stainihard®

Stainihard® NC is a process to harden the surface of (austenitic and duplex) stainless steel, without having a negative effect on its corrosion resistance. In some cases this is even improved.

Technology

High Temperature / Vacuum Brazing

Vacuum Brazing is a process that creates high quality joints under temperatures from about 800°C to 1150°C in a vacuum atmosphere. This also allows for the joining of different materials like for example ceramic to steel.

Technology

Aluminium Brazing

Brazing of Aluminium is a complex process, at Hauck Heat Treatment we can offer several solutions for specific applications.

Technology

Belt Furnace Brazing

Belt Furnace Brazing is a cost-efficient and continuous process that simultaneously applies brazing joints to relatively high volumes of components.

Technology

Physical Vapour Deposition (PVD)

Physical reactions occur from a plasma, which means that exactly through these reactions at very low temperatures (starting at room temperature), layers can be added. PVD can also be applied to all solid materials that you can think of, metal, ceramics, glass as well as plastics. These techniques originate combinations with unique properties.

Technology

Chemical Vapour Deposition (CVD)

The unique properties of the CVD process of Hauck Heat Treatment The Netherlands consist in this process with a very high penetration rate, so that everywhere on a provided surface a layer is created (even in the hair cracks). Also on undercuts and even on more complex geometrical shapes such as metallic foams and the like. The CVD process is generally used to add an improved wear resistance, corrosion resistance or increased friction properties to a component.
