Carburizing is the most important surface hardening process. Carbon is brought to the surface of steel components and diffused to increase tensile strength and hardness. Atmospheric carburizing is for a large number of parts from compressors to valves or gear boxes.
The ALNAT™ solution offers you an active and reproducible heat treatment under nitrogen and methanol. Either in a batch or in a continuous furnace, the methanol is cracked and represents the carbon agent, which is sprayed with nitrogen in the hot zone of the furnace, around 900°C for carburizing.
Our ALNAT™ solutions include gas supply, related gas handling equipment, and a range of services related to the generation, use and control of atmospheres in industrial heat processing furnaces.
