About Gas Nitriding Services

Gas Nitriding is an excellent alternative to liquid nitriding with the proven ability to meet and exceed the capabilities of the liquid treatments.
Liquid and gas nitriding have historically been used to fill different niches, with gas nitriding typically being used for deeper cases which are impossible to produce with liquid nitriding. In actuality, the two processes are nearly identical, as they rely on the same fundamental principles to achieve hardening. Gas nitriding was the first process to be developed, with the first patent being in 1908. Liquid nitriding became popular in the 1930s because it offered better uniformity and required a lower capital investment than the gas nitriding furnaces of the time. These advantages do not hold true in the present day, as modern controlled gas nitriding has advanced to the point where it is displacing liquid nitriding as the method of choice for low temperature case hardening.

The "Post-Oxidation" or "Oxynitriding" process is the gas equivalent of the brand-name QPQ process typically offered with liquid nitriding. With both processes, a black Fe3O4 oxide layer is formed to improve the corrosion-resistance. AIHT's Post-Oxidation Reaction (PROTM) process replicates the QPQ process of liquid nitriding.

Surface hardness is dependent on material chemistry, and thus is equivalent between nitriding processes. Core hardness is dependent on initial tempering condition provided that the nitriding temperature used is significantly below the tempering temperature. The radial growth of the component is related to the amount nitrogen that is diffused into the surface (which can be approximated by case depth), and will be equivalent for comparable case depths.

Gas Nitriding can be tailored to generate cases of virtually any depth including depths shallower than Liquid Nitriding. Since gas nitriding is computer controlled, it is much easier to meet thin case specifications as are commonly found in sour service applications

FAQ's of Gas Nitriding Services:

Q: How does your gas nitriding process achieve precise atmosphere control?

A: Our process uses advanced automatic gas nitriding furnaces, where ammonia flow is carefully monitored and regulated. This ensures consistent atmosphere composition, achieving uniform nitriding results and optimal surface finishing.

Q: What types of materials can be treated using your gas nitriding services?

A: We are equipped to process a broad range of materials, including alloy steel, tool steel, stainless steel, and cast iron. Each material's specific requirements are considered to deliver results tailored to its properties.

Q: When is gas nitriding recommended for component treatment?

A: Gas nitriding is best suited for applications requiring enhanced surface hardness, improved wear resistance, minimized distortion, and superior corrosion protection. It is ideal for tooling, gears, and precision-engineered parts.

Q: Where are your gas nitriding services available?

A: Our gas nitriding services are offered PAN India, covering all major industrial regions. We operate offline, ensuring secure handling and processing at our well-equipped manufacturing facility.

Q: What is the typical process duration and how is it determined?

A: Process duration depends on part size, material type, and the required case depth. We customize timing to client specifications, ensuring each batch meets expected quality standards and timelines.

Q: How does gas nitriding minimize part distortion during processing?

A: The gas nitriding process operates at moderate temperatures (480C - 590C) and promotes uniform case formation. Precise temperature control (5C) greatly reduces thermal stress and minimizes distortion, preserving component geometry.
