Gas Nitriding Furnace

The gas nitriding furnace is a batch furnace used for ammonia based processes. The nitriding process is typically performed when increased surface hardness, wear and abrasion resistance, fatigue strength or corrosion resistance are required. Furnaces can be provided in pit, cover and base or horizontal configurations.

The furnace includes a retort utilizing Inconel or 330 grade stainless steel material. Multiple covers and or bases can be provided to increase system productivity.
