Modern Surface TreatmentsGas Nitriding Nitreg®
NITREG® is a modern heat-treating process, capable of meeting the metallurgical requirements of all nitriding specifications that may have been originally written for salt bath, plasma or traditional gas nitriding. The ability to control the concentration of nitrogen in the surface allows the user to control the growth of the compound layer virtually independently from developing a desirable diffusion zone. This approach facilitates not only meeting any specification requirements, but it also makes it possible to improve on them by allowing tighter tolerances to be satisfied, particularly regarding the thickness and properties of the compound layer.

Modern Surface TreatmentsNitrocarburizing NitregG®-C
Not sure which process or service is right for you? Contact our global team of heat treat experts and let them guide you or fill out the contact form to put you in touch with one of our experts!Nitreg®-C is based on the proven Nitreg® potential-controlled nitriding technology, whose ability to control processes and produce the desired properties of the nitrided layer has revolutionized the whole concept and practice of nitriding. Nitreg®-C has shorter process cycle times than Nitreg® for the same expected specifications and is carried out predominantly on carbon and low alloy materials. It is often specified in industrial applications on the merit of its being an environmentally friendly but equivalent alternative to salt bath nitrocarburizing. The advantage of a KN and KC controlled technology is best evidenced when increased wear and/or corrosion resistance is sought. Such properties of the nitrided case are not only influenced by the thickness and relative phase composition of the WL, but also strongly depend on the relative level of porosity developed in the WL.
Modern Surface TreatmentsIn-process Post-Nitriding/Nitrocarburizing Oxidation ONC®
In-process Post-Nitriding/Nitrocarburizing OxidationWhen resistance to atmospheric corrosion and an attractive black finish are the main requirements, ONC® is the best technology.ONC® is a clean technology that in many instances can replace chrome plating and salt bath nitriding with their inherent problems of pollution and cost. Depending on the type of steel, parts treated with the Nitreg® + ONC processes can easily pass well over 200 hours of salt-spray test per ASTM B117 before the first corrosion spot appears.Not sure which process or service is right for you?

Modern Surface TreatmentsGas Nitriding of Stainless Steels NITREG®-S
Stainless steels respond to nitriding differently than other ferrous alloys, and there are significant differences within the stainless group as well. The primary reason for this is that depending on the chemistry of the steel it will behave differently concerning the kinetics of layer formation, and it is a rather difficult process to control. In other words, unless you know what you are doing you may end up with nothing, or too little, or too much case depth or white layer, or even damaged parts. NITREG®-S is a process in which any stainless steel may be nitrided, with complete control over the formation of nitrided layers. All types of stainless steel can be nitrided.

Modern Surface TreatmentsSurface Hardening of Stainless Steels Nano-S™
Stainless steels have excellent corrosion resistance but possess relatively low strength and wear resistance. NANO-S™ expands their application range to include components that are subjected to intensive wear. NANO-S™ is a surface hardening process that improves the wear and galling resistance of stainless-steel components without affecting the inherent corrosion resistance. The process diffuses nitrogen and/or carbon into the surface of the steel, creating a new phase structure, the S-Phase, which provides extremely high hardness. Because NANO-S™ is a fully controlled process, there is no formation of chromium nitrides/carbides and consequently no loss of corrosion inhibiting properties. The treatment produces a hardened layer that is ductile and up to 25 μm deep (0.001”). Achieved at low temperatures less than 932°F (500°C), NANO-S™ does not induce distortion, which eliminates final machining. Finished parts are uniformly hardened even inside small bores, tight grooves and at sharp edges. Not sure which process or service is right for you?
