Carbonitriding (as well as cyaniding) is the case-hardening process in which both carbon and nitrogen are added to the surface layers of steel at a predetermined temperature usually in the range 800-900° for 2 to 10 hours followed by quenching.
before carbonitriding, to remove rust on the surface, and after grinding the samples were washed by acetone to remove any organic compounds. Both AISI 8620 and AISI 1018 samples were placed in the furnace with an endothermic enriched atmosphere and carbonitriding atmosphere at 850℃ or 800℃ for 2 hours. The carbon
Gas Carbonitriding Furnace. Gas Carbonitriding Furnaces provide most popular methods for treating low carbon and alloy steels to improve the surface hardness and surface durability of steel-alloy components.
Carbonitriding. Almost any furnace which can be used for gas carburising can be adapted for carbonitriding. Temperatures usually 790–845°C. Atmosphere consists of a neutral "carrier gas" (similar to gas carburisation), an "enriching gas", which is the source of carbon (natural gas or propane), and ammonia, which is the source of
Steel Surface Hardening Furnaces, Carburizing Furnace, Carbonitriding Furnace, Nitriding Furnace. For hardening of steel surfaces, several methods can be used. Carburizing is a process of adding carbon to the surface of steel with low carbon content. The carbon will diffuse into the steel and form martensite after quenching.
Carbonitriding. Carbonitriding is undertaken on a similar range of steels although the bulk carbon content can be as high as 0.4 to 0.5%. The process is particularly suited for hardening the surface of components that need a through-hardened core, such as gears and shafts.

Carbonitriding is process of simultaneously inducing both carbon & nitrogen into the surface of a component. Process is performed at lower temperatures (870-880 ) and shorter times than Carburising. Components in this process are less prone to distortion than in Carburising. Case depth from 0.1 mm up to 0.6 mm can be provided.
Case hardening basics: Nitrocarburizing vs. carbonitriding. Confusion surrounding the case hardening techniques of nitrocarburizing and carbonitriding prove the point that it's easy to get lost in the nomenclature behind heat treating processes. That comes with the territory. Metallurgy is complicated.
Vacuum furnace for low-pressure carburising and carbonitriding; are available in three sizes for the treatment of small production batches with low weight and small dimensions. One of the strengths is the precision in the control of the process parameters, which allows excellent results both superficially and metallurgical of the treatments.
Carbonitriding Capabilities on Furnace Variables All our carbonitriding cycles are run in batch-type furnaces for optimum process and lot-control. Our largest furnace capable of performing the carbonitriding cycle has a working dimension of 36" x 42" x 72" and can handle weights up to 7000 pounds.
Carbonitriding refers to a chemical heat treatment process in which carbon and nitrogen atoms penetrate into the surface of the workpiece at the same time. Carbonitriding was first carried out in a salt bath containing cyanide, so it is also called cyanation. The combination of carburizing and nitriding has the following characteristics: 1.

ICBP® Nano: Low Pressure Carburizing Furnace | ICBP ® Nano is the latest product in the range of Low Pressure Carburizing and carbonitriding furnaces, which uses technologies already proven on over 200 installations and 1000 ICBP ® heating cells through out the world.
Internal or intergranular oxidation (IGO) occurs during carburization using endothermic or dissociated methanol atmospheres. Metals processors who eliminate or at least minimize IGO can gain substantial benefits including reduced grinding after carburizing, shortened carburizing cycles, and an improved fatigue-life of gears, shafts and other machine parts.
22.214.171.124 Plasma-assisted LPC and LPCN. Plasma-assisted low pressure carburizing, more commonly termed as plasma carburizing or ion carburizing, and plasma-assisted low pressure carbonitriding are process variations, which utilize an electric field to ionize the hc gases for an enhanced and better controllable carbon transfer (Edenhofer et al.,1991; Gräfen, 1996).
Carbonitriding is carried out over the range 800 ° C to 900°C with a preference for 850°C – 900 ° C. the duration of treatment for a given case depth is a function largely of temperature, provided that a suitable gaseous atmosphere is employed. Furnaces used for carbonitriding are generally of continuous type such as shaker hearth furnace
Gas Carbonitriding Furnace is a proven process for vacuum carburizing with acetylene. One of the most important advantages of this process is high carbon availability, ensuring extremely homogenous carburizing even for complex geometries and very high load densities.
