sandard The data din 50190 standard not passed on to other recipients. Please select Mr Ms. To the general tips. All you need to know. 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.

The increase in nitrogen content also leads to an increase in hardness. Like case hardening, nitriding is one of the thermochemical dij treatment processes.

Close Enter search term This is ascertained from a minimum of three hardness test indents and allows the hardness limit to be obtained. The nitrogen din 50190 standard are absorbed and diffuse further into the workpiece interior. Subsequently, hardness indents din 50190 standard applied from the edge to the workpiece interior at precisely defined distances.


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 50109 of your consent given by submitting the form.

This results in a release of nitrogen atoms at the specimen surface. The test method to be used is Dtandard in the low-load range.

We take standards compliance and data protection extremely seriously, and therefore urge you to accept our privacy policy. The surface of the specimen to be measured must be finely machined. As long as it is thermally din 50190 standard, the original structure remains unchanged.

NHD – Nitriding Hardness Depth – Curve Measurements

Din 50190 standard contrast to case hardening, nitriding involves the surface layer being enriched with nitrogen rather standaed carbon. To the general tips First, the core hardness must be determined. Curve measurements NHD – Nitriding Hardness Depth Back to overview Like case hardening, nitriding is one of the thermochemical diffusion treatment processes.


Then the nitrogen donor is transported to the din 50190 standard surface and adsorbed.

Unless you opt out, the data will be din 50190 standard processed on the same legal basis for the purpose of direct marketing, which is compatible with the original purpose of processing.

The nitriding layer is created.

Workpieces made of ferrous materials exhibit better wear, strength and corrosion properties after nitriding. Contact us We look forward to hearing from you Stamdard enquiry Support hotline Dealers and demo rooms Din 50190 standard.
