Nitrotec®

Surface treatment process for steel and cast iron

Nitrotec® is a surface treatment process for steel and cast iron, carried out in a gas atmosphere furnace at a temperature between 590 ° C and 740 ° C.

Nitrotec® is a worldwide trademarked surface engineering process for the treatment of steels and cast irons

Nitrotec® is carried out in the temperature range of 590-740°C using a gaseous nitrogen and carbon 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 micro 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.

Part of Aalberts industries

Nitrotec® NC is a registered trade mark of Hauck Heat Treatment. Hauck Heat Treatment is part of a global technology company Aalberts Industries, which employs  16.000 people and operates in more than 50 countries worldwide.
