Pit-Type Gas Nitriding Furnace
Vertical-pit nitriding for long automotive and aerospace components.
Also known as: Pit nitriding furnace, Gas nitriding furnace

Overview
The Pit-Type Gas Nitriding Furnace is designed and built by Trimurti Furnace in Nashik, India, for crankshafts, long gears & shafts and extrusion screws. Capacity can be changed as per your requirement. Each furnace is engineered to the customer's parts and throughput by Trimurti Furnace Pvt. Ltd., an ISO 9001-certified manufacturer since 1991.
Pit-type gas nitriding furnace producing a hard, wear-resistant nitride layer on long components. Ideal for shafts, gears, and dies that benefit from minimal distortion.
Engineering Perspective
Hard surface, straight part. The pit advantage applies here too.
Ammonia atmosphere builds a wear-resistant nitride layer without thermal-shock cycling. Combined with vertical hanging, you get a hard surface plus the dimensional stability that long shafts and screws desperately need.
- Vertical hang — no sag distortion
- Ammonia atmosphere control
- Built for crankshafts, dies, extrusion screws
Applications
Built for these processes
- Crankshafts
- Long gears & shafts
- Extrusion screws
