Austentic Fluid Bed Furnace Surface Treatment: | ||
Process | Materials | Advantage |
Austenitic Carburising 600°C – 700°C NH3 / N2 / Hydrocarbon Typical cycle time 30mins – 3 hours
| Low Carbon Low Alloy Steels eg 1020
| Significantly increased wear resistance |
Improved fatigue life. | ||
Freedom from galling and seizing. | ||
Improved corrosion resistance. | ||
No significant dimensional change. | ||
Special Advantage | ||
Short process cycle time e.g. 10-180 mins compared with Qnn Nitriding 12-90 hours. | ||
Effective on all ferrous materials including carbon steels. | ||
A tougher case in comparison with gas nitriding. | ||
