Gas Carbonitriding Furnace

Application Range

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.

Gas Carbonitriding Process is a surface chemistry process, which improves the case depth hardness of a component by diffusing carbon into the surface layer to improve wear and fatigue resistance.

The work pieces are pre-heated and then held for a period of time at an elevated temperature in the austenitic region of the specific alloy, typically between 820 and 940°C.

Product Features

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.

Heating components in sealed atmosphere furnace, and introducing Carbonitriding gases at temperature. accurate temperature and carbon setpoint control.

Gas Carbonitriding allows for accurate control of both the process temperature and carburizing atmosphere (carbon potential).

Vacuum carburizing with acetylene results in a complete carburizing effect along the whole length of the bore because acetylene has a totally different carburizing capability than that of propane or ethylene.

High temperature uniformity throughout all stages of the process. Energy efficient, state of the art heating systems. Equipped with fully automated and programmable industrial controls package. Designed for easy maintenance and minimal downtime.

Carburizing

Carburizing, also referred to as Case Hardening, is a heat treatment process that produces a surface which is resistant to wear, while maintaining toughness and strength of the core.

This treatment is applied to low carbon steel parts after machining, as well as high alloy steel bearings, gears, and other components.Carburizing increases strength and wear resistance by diffusing carbon into the surface of the steel creating a case while retaining a substantially lesser hardness in the core.

This treatment is applied to low carbon steels after machining.Strong and very hard-surface parts of intricate and complex shapes can be made of relatively lower cost materials that are readily machined or formed prior to heat treatment.

Carbonitriding

The process of case hardening by carbonitriding is performed by austenitizing the heat-treat load in a controlled, carbon-rich atmosphere for a length of time commensurate with the case depth requirement, and then quenching the part in oil to harden the developed case.
