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.
Hardening & Tempering
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.
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.
Carburizing is one of the thermochemical processes. During this process the edge of workpieces is enriched with carbon to improve the mechanical properties of the edge layer of the workpiece. Case hardening typically consists of three steps. In the first step, workpieces are exposed to a carbon emitting environment. This increases the carbon percentage at the edge of the workpiece.
The carbon profile and the penetration depth depend on the time at temperature, the amount of supplied carbon, the temperature and the kind of steel used.
In the second phase, quenching (hardening) takes place. This can be performed directly from the carburizing temperature, or after an interstage cooling or new heating to a new material-specific curing temperature.
The third step is tempering and mainly serves to diminish the highest stresses in the structure and to diminish the grinding crack sensitivity.
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.
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.
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.
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.
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.
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.
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.
