Carbonitriding furnace

Carbonitriding furnace is a kind of equipment used for metal surface treatment, which mainly forms a layer of carbonitride on the metal surface through chemical heat treatment process. The main function of this equipment is to make carbon and nitrogen atoms penetrate into the metal through a specific process under high temperature environment, thereby improving the mechanical properties of the metal. Carbonitriding technology is widely used in industry and is often used to manufacture high-precision, high-speed and long-life bearings. This technology can give the material high strength, high wear resistance, high stability and excellent fatigue resistance.

Carbonitriding is usually done at lower temperatures, typically between 850-900°C, while carburizing is usually done at 900-950°C. The lower temperatures help reduce workpiece deformation and grain growth.

 

The depth of carbonitriding layer is usually between 0.2-0.8mm, which is shallower than the carburized layer. This makes carbonitriding more suitable for workpieces that require a shallower hardened layer.

 

Carbonitriding can be carried out at a lower temperature, the workpiece is not easy to overheat, and the deformation after quenching is small. In addition, carbonitriding reduces the austenite formation temperature, making the quenching process smoother and further reducing deformation.

 

Carbonitriding has a faster penetration rate, usually completed within 1-4 hours, while nitriding takes dozens of hours. This greatly shortens the processing time and improves production efficiency.


Carbonitriding significantly improves the hardness and wear resistance of the workpiece surface, while also improving the fatigue strength and fatigue resistance of the workpiece. This is very beneficial for workpieces that require high strength and high wear resistance.
