Heat Treatment Services

Heat treatment in vacuum

We perform hardening and tempering of tool steels to provide the mechanical properties required in a wide variety of applications. The advantages of the process are minimal deformations, high repeatability of the process and unchanged bright surface of the products. Ordinary tool steels as well as high-speed steels and powder materials can be vacuum treated. Tempering in a vacuum furnace is computer-controlled, which enables control and archiving of all heat treatment processes.

The company has 3 state-of-the-art vacuum furnaces from the German manufacturer SCHMETZ, where we can heat-treat products up to dimensions of 800x800x1,600 mm and a maximum batch weight of 2,500 kg.

For special applications with the aim of transforming residual austenite into martensite (increasing hardness and wear resistance), we also have the option of subcooling after quenching to a temperature of -145 ° C.

Tempering in oil or salt bath

Carbon, low-alloy steels and cementation steels are hardened in the oil. In the salt bath we are limited by the dimensions 1000 x 250 x 50 mm.

Induction hardening and annealing

Induction hardening is mainly low-alloy steels where we want a hard surface and at the same time a tough core. Examples of use are bolts and battens. For certain applications, tool steels are annealed in order to improve toughness under dynamic loads.

Annealing and normalization

It is used as a pre-treatment to reduce internal stresses, reduce hardness and increase machinability.

Cementation and carbonitriding

We process steel products for cementation, where high wear resistance of the surface is required, as well as a tough core.

Nitriding and nitrocarburizing

Industrial applications with special requirements for wear resistance as well as corrosion resistance.
