Environmentally Friendly Surface Engineering
Technical Overview

Nitrotec® is a worldwide trademarked Surface Engineering Process for the treatment of steels and cast irons carried out in the temperature range of 550 -740ºC using a gaseous nitrogen bearing atmosphere. 

The treatments develop iron nitride surface compound layers between 5 and 50 um thick, supported by a nitrogen rich diffusion zone in the substrate.

We have a global network of sister companies and licensees who are specialists in heat treatment and provide our Nitrotec process. If you are interested in joining them, please contact us directly. 

From the application of specific treatment temperatures, times and nitrogen potential, the structure, composition and hardness of the compound layer and the sub-surface diffusion zone, are controlled.

An innovative oxidation technique, combined with specially formulated aqueous quenchant and organic sealant are incorporated depending on the engineering requirements of your specific application.
