Since plasma is very effective in removing the passive layer of a chromium oxide formed naturally on the surface of stainless steel, UltraGlow® Ion Nitriding is widely used to harden (especially selective harden) stainless steel parts.
Chromium and other metal nitrides formed in stainless steels have good thermal stability and maintain very high hardness at elevated temperatures to 1100ºF. Therefore, UltraGlow® Ion Nitriding replaces chromium plating in many applications (especially in the power-generation industry) where a nitrided layer does not peel off from the surface, as it often does with chrome plated parts, because there are no thermal expansion problems. Also, mechanical masking is frequently used in many of these applications. Hardness of the nitrided layer in stainless steels is very high (> 70 HRC equivalent), but as in all AISI 300 series stainless steels, there is an abrupt change of hardness between the nitrided diffusion layer and the core (Figure 1).
