To the general tips.

This results in a release of nitrogen atoms at the specimen surface. The nitrogen atoms are absorbed and diffuse further don the workpiece interior.

Please select Mr Ms. Determination of the nitriding hardness depth is defined in standard DIN Close Enter search term Subsequently, hardness indents are applied from the edge to the workpiece interior at precisely defined distances.

The data are not passed on to other recipients. By using the website, you agree.

All you need to know. As long as it is thermally stable, the original structure remains unchanged.


The increase in nitrogen content also leads to an increase in hardness. To the general tips First, the core hardness must be determined.

The nitriding hardness depth is derived from the curve representing the hardness over distance from the surface by measuring the distance from the surface to the calculated hardness limit.

Unless you opt out, the data will be further processed on the same legal basis for the purpose of direct marketing, which is compatible with the original purpose of 501900. Then the nitrogen donor is transported to the workpiece surface and adsorbed.

NHD – Nitriding Hardness Depth – Curve Measurements

Contact us We look forward to hearing from you Your enquiry Support hotline Dealers and demo rooms Newsletter. The nitriding layer is created.

This is ascertained from a minimum of three hardness test indents and allows the hardness limit to be obtained. Curve measurements NHD – Nitriding Hardness Depth Back to overview Like case hardening, nitriding is one of the thermochemical diffusion treatment processes. After you submit the contact form, the above-mentioned data will be processed by the party responsible for data protection for the purpose of processing your request on the basis of your consent given by submitting the form.


The test method to be used is Vickers in the low-load range. The surface of the specimen to be measured must be finely machined.

Further information can be found in our privacy policy. We take standards compliance and data protection extremely seriously, and therefore urge you to accept our privacy policy. In srandard to case hardening, nitriding involves the surface layer being enriched with nitrogen rather than carbon. First, the core hardness must be determined.

Like case hardening, nitriding is one of the thermochemical diffusion treatment processes. Workpieces made of ferrous materials exhibit better wear, strength and corrosion standafd after nitriding.
