Nitrotec® is a worldwide trademarked surface engineering process for the treatment of steels and cast irons carried out in the temperature range of 590 -740°C using a gaseous nitrogen bearing atmosphere.

The treatments develop iron (carbo)nitride surface compound layers between 5 and 50 µm thick, supported by a nitrogen/carbon rich diffusion zone in the substrate.

By choice of treatment temperature, time and nitrogen potential of the atmosphere, 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 a specific application.

The Nitrotec® process is used to enhance the surface and strength characteristics of a range of carbon and low alloy steels. Wear resistance, improved fatigue performance and excellent corrosion resistance are among the properties conferred by this modern surface treatment technology. Such improvements in performance can significantly reduce the manufacturing and materials cost of components, a fact proved repeatedly by the automotive industry on pressed parts.
