Thread: Nitriding

I used to get a lot of nitriding done at heat treatments ltd of injection mould and machine parts. Excellent process that required very little rework after treatment if any. 65 HRC surface hardness around 5 thou deep and can be double dipped for extra depth. Not sure about the corrosion resistance bit while It did improve it was definitely not like stainless. We still used stainless for mouldings corrosive plastics.
