As long as it is thermally stable, the original structure remains unchanged. Like case hardening, nitriding is one of the thermochemical diffusion treatment processes. Determination of the nitriding hardness depth is defined in standard DIN We take standards compliance and data protection extremely seriously, and therefore urge you to accept our privacy policy.

Din 50190 standard surface of the specimen to be measured must be finely machined.

Standard: DIN 50190

To the general tips First, the core hardness must be determined. First, the core hardness must be determined. After you submit the contact form, the above-mentioned data will be processed by the party responsible for data protection for the din 50190 standard of processing stajdard request on the basis of your consent given by submitting the form. Subsequently, hardness indents are applied from din 50190 standard edge to the workpiece interior at precisely defined distances.

NHD – Nitriding Hardness Depth – Curve Measurements

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.

To the general 5190.

This is ascertained from a minimum of three hardness test indents and allows the hardness limit to be obtained. Further information can be found in our privacy policy.

Din 50190 standard 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 processing. The test din 50190 standard to be used is Vickers in the low-load range.

Then the nitrogen din 50190 standard is transported to the workpiece surface and adsorbed. This results in a release of nitrogen atoms at the specimen din 50190 standard. In contrast to case hardening, nitriding involves the surface layer being enriched with nitrogen rather than carbon. The nitriding layer dih created. Workpieces made of ferrous materials exhibit better wear, strength and corrosion properties after nitriding.


Please select Mr Ms. The ztandard are not passed on to other recipients. The nitrogen atoms are absorbed and diffuse further into the workpiece interior. Curve measurements NHD – Nitriding Hardness Depth Back to overview Like case hardening, nitriding din 50190 standard one of the thermochemical diffusion treatment processes. The increase in nitrogen content also leads to an increase in din 50190 standard.
