Nitriding powder

Workpieces are placed into an annealing box together with the nitriding powder and activator and the lid is closed and sealed
Powder nitriding or powder boriding causes a thin cover layer to form against friction wear and fatigue resistance is substantially increased
At approx. 550 °C an extremely thick cover layer forms (up to 1000 HV) which covers the hardened steel or the carburized edge layer. The activator improves process conditions.
The process duration at 550 °C is at least 10 hrs
For all steels and cast iron, such as hot work steel matrices, injection molding dies, wear parts and machine components
Anti-nitriding paste to protect areas which should not be processed
Boriding powder upon request
