Benefits of Carbonitriding Heat Treatment
Carbonitriding is one of the processes of gas heat treatment. The process involves the introduction of carbon and nitrogen into the surface of the steel. This process is similar to gas carburizing, which is a process in which carbon is infiltrated into the surface and carburized, then hardened by rapid cooling (Quenching) at a lower temperature. The difference between these two processes is the substance added to the steel surface and the temperature used.
Carbonitriding is a process in which carbon and nitrogen are simultaneously infiltrated into the surface of steel at a temperature of about 800℃ to 880℃, lower than ordinary gas carburizing (850℃ - 940℃). After the part has been heat-treated, then the quenching part is needed to immediately start. Quenching is also the critical step in the carbonitriding heat treatment which can be cool heated metal in water, oil, or air in order to obtain desired material properties.
You're probably starting to wonder how this difference affects your products. And why is carbonitriding a better alternative? Thai Parkerizing will answer your questions today.
Purpose of Carbonitriding heat treatment process
The purpose of carbonitriding is to create a hard, wear-resistant surface layer while maintaining the toughness of the underlying metal. The carbon and nitrogen atoms form nitrides and carbides in the metal, which are very hard and wear-resistant. However, the hardened case is not an additional layer on top of the steel. The carbonitriding process alters the top layer of the component so the original dimensions are retained. The process is suitable for non-alloy steel and low carbon steel that would not achieve a hardened surface in standard gas carburizing.
Advantages of carbonitriding heat treatment process
As previously mentioned, the lower temperature used in the carbonitriding process allows treating non-alloy steel such as SPCC and low carbon steel which cannot be applied by gas carburizing. Therefore, it also reduces the cost of the material. This point can be considered as one of the advantages of the carbonitriding process. Nevertheless, it is not the one and only benefit. The process also provides the benefits as follow:
- Available to control surface hardness and case depth
- Available in 3 types of quenching oil (cold / semi hot / hot)
- Improve hardness, toughness, and impact strength
- Improve wear resistance ability
- Improve fatigue strength

Frequently Asked Questions
Carbonitriding is one of the heat-treating processes under various gas atmospheres and temperatures mainly to improve hardness, wear-resistance, and fatigue or tensile strength properties of industrial parts in order to prolong their lifespan and improve their properties to suit specific usability.
Carbonitriding is a process in which carbon and nitrogen are simultaneously infiltrated into the surface of steel at a temperature of about 800°C to 880°C, lower than ordinary gas carburizing, and then quenched and hardened. In gas carbonitriding, NH3 gas is added to a normal gas carburizing atmosphere, and nitriding and carburizing are performed simultaneously by
the N component decomposed from NH3. Since the hardenability is improved by nitriding, it is possible to treat non-alloy steel such as SPCC and low carbon steel which cannot be applied by gas carburizing, and the reduction of material cost is also a great advantage. Since it can be quenched at a lower temperature than gas carburizing, deformation, and distortion due to heat treatment can be reduced. Characteristics of gas carbonitriding are including
- Applicable steel type: Low carbon steel (low carbon steel such as SP material, SS material, S10C), case hardening steel (low carbon alloy steel such as SCM / SCr / SNCM)
- Quenching is possible at low temperatures, reducing quench deformation (Excluding case-hardened steel)
- Since the hardenability is improved by the influence of nitrogen, quenching becomes easy even with carbon steel, which is advantageous in terms of quenching cracking.
- Compared to gas carburization, the abnormal hardening layer on the outermost surface is suppressed, and a uniform hardened layer can be generated.
- Improved temper softening resistance compared to gas carburizing.
This process is important because it can improve the mechanical properties of the metal, such as its hardness and toughness. In addition, carbonitriding can also help to protect the metal from corrosion.
The carbonitriding process usually applies with power units parts such as engines, transmissions, and differentials parts (connecting rod, crankshaft, transmission gear/shafts, CVT pulley shaft, driveshaft, constant velocity joint parts, final gear, differential side gear, etc.)
