The Gas Nitriding Process
UltraGlow® Gas Nitriding is a case-hardening process whereby nitrogen is diffused into the surface of a solid ferrous alloy by holding the metal at a suitable temperature in contact with a nitrogenous gas, usually ammonia.
Benefits of This Heat Treatment:
- Extends part/tool life
- Adds performance, fatigue strength and endurance
- Enhances surface lubricity
- Reduces erosion
- Increases material flow in molds and dies
- Improves corrosion resistance
- No post-process machining
- Improves wear resistance
- Minimal growth/distortion
- Precise and versatile
- Phase controllable compound zone (or white layer)
- For additional corrosion resistance, Advanced Heat Treat Corp's UltraOx® treatment can be combined with the gas nitriding process. Click here to learn more about ULTRAOX.
