MIHEU d.o.o. is a family business with over 40 years of experience in the field of heat treatment of steel.


Throughout its existence, the company has grown and developed in order to pursue the individual needs of customers. Starting as a workshop for hardening and tempering and case-hardening, it has expanded into a heat treatment center with a wide range of additional services. The company continues to grow, while maintaining its flexibility and responsiveness of smaller systems.

Heat treatment solutions range from traditional oil hardening and tempering in pit furnaces to the most advanced systems for the processes of carburizing, carbonitriding, nitrocarburizing, vacuum furnace hardening and all kinds of nitriding, gas as well as plasma nitriding. Investing in superior equipment and highly qualified personnel, together with many years of experience and knowledge, sets the main guideline of the company to achieve the best results.

Additional services represent a wide range of treatments that enable the company to find the most appropriate solution for customer's specific requirements. This covers the processes of annealing, quenching (oil or water) and normalization, sandblasting and bluing, dimensional control and straightening, and above all, CNC machining on high-performance milling and grinding centers. Advising the customer to find the right solution is the basic approach to a successful partnership.

In our own laboratory, we monitor heat treatment quality with advanced instruments using hardness and microhardness measuring equipment and optical microscopes to inspect microstructures. These analyses help us confirm that results are really in accordance with customers' specifications.

Technical equipment provides only a tool, while know-how and experience make the real driving force in seeking the best solutions for individual customer's needs. We are proud of our business ties with several business partners that have continued for many years, giving us great motivation for the future. Join us and experience the wide selection and great quality of our heat treatment solutions.

We build our presence on tradition and long years of experience – we plan our future with continuous investments in know-how and new technologies.
