As a result, the corrosion resistance and hardness of the surface layers increase. In general, HTGN has usually been applied to Cr based austenitic, martensitic and duplex stainless steels, which have high nitrogen solubility in the austenite phase.
Bilang isang resulta, ang kaagnasan paglaban at tigas ng mga layer sa ibabaw taasan.Sa pangkalahatan, ang HTGN ay karaniwang na-apply sa CR batay sa austenitic, martensitic at duplex hindi kinakalawang steels, na may mataas nitrogen solubility sa austenite phase.
