hardening for you

Hardening is a type of heat treatment that involves heating the material to the quenching temperature, followed by tempering, and finally cooling at a supercritical rate. It is used to enhance the mechanical and physical properties of the material, particularly its hardness and wear resistance. In PRIKNER heat treatment shop, we perform several types of hardening.

In addition to precise conventional steel hardening, we provide a range of specialized variants of this process, including hardening in a protective atmosphere and vacuum quenching, which allow specific material properties to be achieved according to specific customer requirements. We are one of the few in the Czech Republic to carry out bainitic quenching, and our strengths also include cryogenic metal processing and knife blade hardening.

We are capable of hardening heat treatable steels, tool steels, stainless steels, high-speed steels and steels for special applications.

Our extensive experience, expertise and state-of-the-art technology go into every metal heat treatment process, enabling us to offer a wide range of hardening options to meet the requirements of even the most demanding clients.



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
