Ion Nitriding Furnace for Stainless Steel & Titanium Alloy – Passive Film Removed Automatically, Har

September 29, 2026
This video shows the full ion nitriding process for stainless steel and titanium alloy. Ion nitriding uses glow discharge ion bombardment to automatically remove the passive film on stainless steel surfaces – no sandblasting or acid pickling pre-treatment required.

For stainless steel: Low-temperature ion nitriding (350–450℃) forms an “S-phase” case, improving surface hardness while maintaining corrosion resistance. 316L stainless steel achieves optimal hardness at 500℃, 3 hours, and 1.6 mbar nitrogen pressure, with a hardness increase of approximately 143%.

For titanium alloy: A gradient nitride layer (TiN/Ti₂N) forms on the surface, offering high hardness and wear resistance. Ti-6Al-4V reaches 764 VHN at 500℃, 4 hours, and 1.6 mbar, an increase of approximately 153% compared to the substrate.

Key advantages of the ion nitriding furnace:

No pre-treatment needed – stainless steel and titanium alloy loaded directly

Uniform case with controllable compound layer structure

Minimal distortion, suitable for precision parts

Energy-saving and eco-friendly, low gas consumption

Applications: stainless steel parts, titanium alloy parts, molds, gears, lead screws, medical devices, etc.
