What is plasma ion nitriding?
Plasma Ion Nitriding [PIN] is the most established technique to render hard case for many steels of industrial use. Hard case is created by diffusing nitrogen in steels in the presence of Plasma to impart surface hardness for a wide variety of Applications. Plasma nitriding is high precision, environment friendly technology as compared to liquid nitriding and gas nitriding.
