Thermal processes

Hardening

The process of thorough hardening consists of combination of hardening and high tempering.

Depending on the cooling medium used, we have the following technologies:

   – under protective atmosphere with oil quenching

   – in a vacuum atmosphere with gas quenching (max 25 bar abs)

High tempering processes are carried out in a protective or nitrogen atmosphere.

We can distinguish typical, gradual, isothermal, surface finish hardening. Depending on the type of hardening, the steel microstructure is martensite or bainite.

 

Annealing

The annealing process involves heating the material to a predetermined temperature, soaking at this temperature and slow cooling under a protective atmosphere or in air. Depending on the process parameters, we can distinguish between homogenizing, complete, normalizing, spheroidizing, recrystallizing and stress relieving annealing.

In the scope of annealing, we offer annealing with:

   – slow cooling in a protective atmosphere

   – slow cool in air atmosphere

   – slow cool under vacuum

   – slow or forced cool under nitrogen or argon

Tempering

Tempering is a heat treatment process consisting in heating the previously hardened steel to a certain temperature, withstanding and slow air cooling. The purpose of tempering is to remove the stresses created during hardening, to change the physical properties and, above all, to increase impact resistance at the expense of reduced hardness.

We can distinguish three types of tempering:

   – Low tempering at 150-250°C, applied in order to reduce hardening stresses. It does not             significantly influence hardness reduction.

   – Average tempering at 250-450°C, applied in order to provide significant strength and               elasticity while maintaining sufficient resilience and ductility.

   – High tempering at 450-Ac1, applied in order to significantly reduce hardness and obtain           good flexural properties.

Thermochemical processes

Carbonitriding

It consists in simultaneous enrichment of the part’s case with carbon and nitrogen. It is a modified carburizing process, carried out at lower temperatures (775 – 900°C) and for a shorter time. The process is used to increase the wear resistance of lightly loaded, small-sized products. We offer carbonitriding in an enriched, protective carburizing atmosphere.

Gas carburizing

Gas carburizing is a thermo-chemical treatment consisting in heating steel parts to the temperature of 870 – 1000 ° C and heating them in a carburizing atmosphere. The purpose of carburizing is to enrich the surface layer with carbon and, as a result, increase its hardness and abrasion resistance while maintaining a ductile core. Directly after carburizing, hardening and tempering are most often carried out.

We offer carburizing in a protective atmosphere according to the following stages:

   – Direct: (carburizing -> quenching -> tempering)

   – Single: (carburizing -> slow cooling -> heating to austenitization temperature along with            hardening -> tempering)

   – With isothermal stop: (carburizing -> cooling down to the set temperature -> heating to             austenitization temperature with quenching -> tempering)

   – Double: (carburizing -> quenching -> heating to austenitizing temperature along with                 quenching -> tempering)

Single carburizing processes or with an isothermal stop are especially dedicated when it is necessary to perform, respectively: additional soft machining, austenite grain refinement (the so-called perlitization process).

Distortion Control

Straightening

We have fully automated lines for straightening round and flat parts, as well as details of complex geometry (shafts, profiles). The lines are endowed in integrated sensor for internal crack detection.

   – 160kN pressure force

   – Workpiece lengths: 200-1000 mm

   – Workpiece weight: 0.5-5 kg

   – Straightening accuracy: up to 0,01 mm

Crack detection

Eddy current

A fully automatic crack detection device. The scope of application of the crack testing machine includes 100% testing of key safety components such as drive shafts, wheel hubs or brake discs. Non-destructive vortex tests are performed by fully scanning the electromagnetic fields of the respective areas to eliminate the presence of cracks in the details.

Washing

One of the most important elements in the heat treatment process is washing before and after the process. We are aware of that! That’s why we have high-performance chamber units for parts cleaning.

Water – Based

Cieffe WCF-8/2 / E-R – chamber cleaning device with two tanks for cleaning parts before the process. The advanced technology of used water-based detergents makes the details before the process perfectly washed, which has a decisive influence on the quality of the heat treatment while taking care of the environment.

 

Hydrocarbon – based

EMO VAIOCS – high-performance hydrocarbon cleaner for cleaning the right part after heat treatment. It is characterized by excellent degreasing (vacuum degreasing) and washing features, which plays a crucial role in the subsequent production steps, affecting the quality of the finished product surface.

Sandblasting

Manual and automatic sandblasting machine MHG Strahlanlagen is available and characterizes by high performance and very good results of blasting the sandblasted parts.

Laboratory-Metallography

Modern laboratory equipment enabling the implementation of:

   – Sample preparation, including mounting and polishing

   – Hardness measurement by the methods of Vickers, Rockwell, Brinell

   – Measurement of microhardness with measurement of the hardened layer CHD and                     NHT Microstructure analysis

   – Analysis of the chemical composition of the material using a spectrometer

We offer laboratory services as part of the heat treatment technology services and on individual orders.
