We undertake Carbo Nitriding heat treatment for various alloy parts using pit type gas carburizing furnaces. The furnace is integrated with auto tuning microprocessor based ramping controller along with soak timer, which ensures execution of flawless service. In this process, both carbon and nitrogen are diffused thus, making it suitable for low carbon alloys of steels. Carbonitriding takes place at 760-870 C (1400 - 1598 F) where alloys parts are heated in an atmosphere of hydrocarbon, which has methane or propane and is mixed with Ammonia (NH3).
