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.

Summary
-
A unique gaseous
Ferritic-Nitrocarburizing and Oxidizing process
-
Developed to enhance wear
resistance and fatigue strength
-
Increases tensile, yield,
fatigue and impact strength
-
Low process temperature greatly
reduces distortion
-
Proprietary polymer dip adds
superior corrosion protection.
-
The coating in the porosity of
the nitrocarburized case provides a durable
corrosion resistant surface that
resists wear and will not chip or scratch.
