The increase in nitrogen content also leads to an increase in hardness. 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 din 50190 standard processing.

NHD – Nitriding Hardness Depth – Curve Measurements

Determination of the nitriding hardness depth is defined in standard DIN The test method to din 50190 standard used is Vickers in the low-load range. Close Enter search term To the general tips.

Like case hardening, nitriding is one of the thermochemical diffusion treatment processes. Workpieces made of ferrous materials exhibit better wear, din 50190 standard and corrosion properties after nitriding.


In contrast to case hardening, nitriding involves the surface layer being enriched with nitrogen rather than carbon. Subsequently, hardness indents are applied from the edge to the workpiece interior at precisely din 50190 standard distances. The nitriding layer is created. As long as it is thermally stable, the original structure remains unchanged.

This is ascertained from a minimum of three hardness test indents and allows the hardness limit to be obtained. 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 din 50190 standard.

Standard: DIN 50190

All you need to know. The nitrogen atoms are absorbed and diffuse further into the workpiece interior.

din 50190 standard To the general tips First, the core hardness must be determined. This results in a release of nitrogen atoms at the specimen surface. The data are not passed on to other recipients.
