Our company offers hardening, vacuum tempering, nitriding, induction surface hardening high frequency, quenching in protective atmosphere, annealing.

We offer heat and chemical-heat treatment of steels and other metals, consulting activities in the field of materials application and their heat treatment, refining, hardening in various hardening media including vacuum hardening, cementation and nitriding.

We are a heat treatment company and use our extensive experience in the industry from the past years. Quenching in conjunction with tempering produces the final properties of the tool, making this process the most important operation in production and recovering the value of the material used.

We offer induction hardening. We provide heat treatment of metal materials by induction technology. We provide medium and high frequency hardening, supply of technologies. We manufacture complete equipment, application machines, control systems. We provide refurbishment services. We sell copper tubes and more.

We deal with heat treatment of metals. We provide simple bath hardening, vacuum hardening followed by freezing, cementation, vacuum annealing and more.

We offer hardening and ashing, refining, annealing, cementing, blackening, straightening and sandblasting. Heat treatment is carried out in chamber, wagon chamber and shaft furnaces.

We focus on heat and chemical heat treatment of metals. We offer hardening, annealing, tempering, cementing, nitriding and surface hardening. We process formed, cast, structural and tool steel, cast iron and non-ferrous metals in a wide range of processes.

Provision of heat and chemical-thermal treatment of metals. Offer hardening, refining, tempering, cementing and annealing of steel and cast iron.

We deal with heat and chemical-thermal treatment of metals. We carry out hardening, annealing, refining, nitriding, carbonitriding, tenifer, oxidation, cementing, nitrocementing, blackening, blasting, plating, chemofinishing, ceramofinishing, straightening, freezing.

Carbonitriding technology in ionic liquid TENIFER and ARCOR. PVD and PACVD coating. Slip sleeves for demanding applications. Salts and furnaces for heat treatment (quenching, annealing, tempering), protective pastes, blackening chemicals. Subsidiary company. HEF Groupe with technical support in the Czech Republic.

We deal with heat and chemical-thermal processing of metals. We carry out hardening, annealing, refining, nitriding, carbonitriding, tenifer, oxidation, cementing, nitrocementing, blackening, blasting, plastering, chemofinishing, ceramofinishing, straightening and freezing.

The main heat treatment technology is nitriding in a gaseous atmosphere. As a complementary service to the nitriding process, we offer surface oxidation after nitriding. There is also the possibility of protecting parts of surfaces, threads, holes before nitriding, annealing, tempering and inter-operative stabilization to remove stresses.

We provide heat treatment of metals, preheating and annealing of welded joints. We offer sales and rental of annealing sources. Manufacture, sale and rental of heating elements for electro resistance heating. We provide hardness measurement of steel materials. We provide realization of electro resistance heating of steel materials.
