handling the toughest

Annealing involves controlled heating of the metal to the annealing temperature, followed by holding and slow cooling to room temperature. It allows for the reduction of internal stresses in the material, improves its ductility, reduces hardness, and thus facilitates machining. The aim of annealing, which can occur with or without grain recrystallization, is to achieve equilibrium in the material's structure.

In PRIKNER heat treatment shop, we offer soft annealing, normalizing, stress relieving annealing, spheroidizing annealing, isothermal annealing, solution annealing, homogenization annealing, recrystallization annealing, and annealing for magnetic properties.

With these methods, we can process steels of almost any grade for use across industries.

All types of annealing are carried out using the latest processes and technologies. Thanks to our extensive experience and expertise in the field, we are able to tailor the processes to meet the individual needs of our customers. They can thus rely on the final product always matching their requirements and expectations.

World-unique furnace

In the PRIKNER heat treatment shop, we have one of the few furnaces in the world equipped for hardening with a nitrogen overpressure of 25 bars. Thanks to it, we are able to treat a much wider range of materials than other companies in the Czech Republic and beyond.



We are industry leaders
since 1990

For over three decades, we have been heat treating metals for clients across industries. Every new project is a challenge and an opportunity for us to prove time and time again that we are at the top of our field.

We innovate for the benefit of our customers
and the environment

We continuously improve our processes. We collaborate with the Czech Technical University in Prague and the Slovak University of Technology in Bratislava on long-term research projects in the field of heat treatment of materials.

We think
about every project

Our goal is to deliver the highest quality product possible, which is why we approach each order individually, striving to find the best solution for every client.

We carburize
to great depths

We are the only heat treatment shop in the Czech Republic to master the technology of vacuum carburizing to great depths. This allows us to deliver a product with excellent hardness and exceptional durability.

We demonstrate our qualification
and results

We hold the TUV MANAGEMENT SERVICE certification according to the ISO 9001:2016 standard and the prestigious Company of the Year award of the Hradec Králové Region for 2016.

We provide expert consulting
and advice

No project is too small or too big for us. We are happy to discuss yours and offer guidance on the optimal course of action.
