Find the Right Gas Nitriding Furnace for the Ammonia Based Processes

We recognize that the process of diffusing the nitrogen to the surface of a ferrous is known as nitriding. The process will raise the hardness of the surface, wear, abrasion resistance, corrosion resistance, and fatigue strength. Maharith Thermal Pvt. Ltd. has been working for many years in the industry for batch and continuous equipment. We manufacture the gas nitriding furnace a type of batch furnace that can be used for ammonia-related processes. The furnace will be handy for the works in the auto parts, gears, tool, die, plastics, aluminium extrusion, casting, military industry, and more.

Frequently Asked Questions (FAQs)

What is the process of gas nitriding?
Gas nitriding is a surface hardening treatment applied to steel parts. It works by heating the part in an atmosphere rich in nitrogen so that nitrogen can go into the outer layer of the metal. This hardens the surface and makes it more wear-resistant, but leaves the inside of the part mostly unchanged. Customers usually look for this process when they want better part life without major distortion.
Gas nitriding usually takes several hours, and for deeper cases it can take much longer. Some work might take a few hours to complete, while others might take many hours or even up to around 100 hours, depending on the material and depth required. Timing depends on the part. Best planned after reviewing the job requirements.
Gas nitriding is done at a relatively low heat-treatment temperature, usually around 500 to 590 degrees centigrade, or roughly 950 to 1050 degrees Fahrenheit. This lower temperature is one reason many customers choose it, because it helps reduce warping and size change in finished parts. It is a controlled process, not a high-heat one.
Nitriding increases surface hardness and wear resistance, helping metal components to last longer. It also allows parts to better cope with repeated stress and prevents them from wearing out too fast. Another big plus is that it normally changes shape very little, which is helpful for precision parts.
The main difference is the medium used for the treatment. In gas nitriding, the medium is an ammonia-based gas, and in liquid nitriding, a salt bath. Both are used to harden the surface, but gas nitriding is often preferred when better control and cleaner processing are desired for industrial parts.
The hardness after nitriding depends on the metal, the process used, and the depth of treatment. In some cases, the surface can become very hard. However, exact hardness varies from part to part, so it is always best to check with respect to the material and application.
Gas nitriding involves heating the part in a furnace and exposing it to a nitrogen-bearing gas (usually ammonia), whereby nitrogen diffuses into the surface. The gas supplies the nitrogen. The heat makes the diffusion process possible. This is why the furnace must keep both temperature and atmosphere under close control for a good result.
Yes, but only to a limited extent. Since nitriding changes the surface layer of the metal, light removal can be done by grinding or machining, but you cannot simply reverse the process. If too much of the nitrided layer is removed, the benefits will be lost. That is why customers usually ask carefully before treatment if the final dimensions and finish matter.
