- Gas 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 specification requirements, but it also makes it possible to improve on them by allowing for tighter tolerances, particularly regarding the thickness and properties of the compound layer.

The NITREG® Advantage

• Controls the thickness of the compound (white) layer and its properties
• Eliminates closed nitride networks within the diffusion zone
• Excellent control of the case depth

• Uniformly hardened even small bores, tight grooves and sharp edges

• Excellent control of surface hardness
• No parts distortion
• Very high level of process repeatability
• Green technology, no waste pollution
