UltrawearPlus®
Ferritic-Nitrocarburizing / Oxidizing Process with Polymer Coating
A sub-critical nitrocarburizing process, in combination with a protective coating application, greatly improves the corrosion resistance of a wide range of carbon, alloy steel and cast iron parts while also improving their wear resistance, fatigue, impact and yield strength.

FNC Process Cycles
Process temperatures range between 1000° F and 1200° F. Cycle times can vary between 30 minutes and 14 hours, depending upon the material being processed and the case depth and properties desired.

Oxidation Cycle
At the end of the nitrocarburizing cycle, a controlled oxidation step in the same furnace is the usual process, this develops and Fe304 iron oxide layer providing an aesthetic protective finish. This cycle is typically 15 to 30 minutes ling and is performed at 850° F to 1050°F.
