Gas Nitriding
With gas nitriding, the edge of a workpiece is either finished with nitrogen or with nitrogen and carbon (gas nitrocarburising) in a gaseous atmosphere. To improve the tribological characteristics of the component, it can then be oxidised.

Nitriding, gas nitriding and gas nitrocarburising : Innovative surface treatment.
We are one of the leading suppliers of nitriding and gas nitriding processes in metal processing. Our specialised processes offer improved surface hardness, increased wear resistance and corrosion resistance suitable for a wide range of industrial applications.
Nitriding: Basics and benefits Nitriding is a process in which nitrogen is introduced into the surface of metal parts to create a hard and wear-resistant layer. This process enables us to significantly increase the durability and service life of your components. The hardened layer created by nitriding is extremely resistant and is ideal for applications that are subject to high loads and wear.
Gas nitriding at the Lingenhöle company
Gas nitriding is a special form of nitriding in which nitrogen is used in the form of a gas, typically ammonia gas. At Lingenhöle, we carry out gas nitriding in precisely controlled environments. This process enables us to achieve accurate results that meet the high quality standards of our customers.
Why gas nitriding?
Low deformation: Gas nitriding is carried out at relatively low temperatures, which minimises the deformation or distortion of metal parts.
Precise control: Thanks to our advanced technology, we can precisely control temperature, gas flow and process duration to ensure consistent quality.
Increased wear resistance:
Gas nitriding increases the resistance of the surface to abrasion and corrosion, which leads to a longer service life for the components.
Applications of gas nitriding
Lingenhöle offers gas nitriding for various industries, including automotive, mechanical engineering and aerospace. Our services are suitable for a wide range of metal parts such as gears, shafts, valves, bearings and tools. If your parts are exposed to high mechanical loads and wear, gas nitriding is an excellent solution.
