Very hard indenters of defined geometries and sizes are continuously pressed into the material under a particular force. Hardness conversion table in general use 2.

Webster hardness conversion table 7. This is similar to using various indenter geometries and test loads in Rockwell e. Pin Brinell hardness calculator Even in the case of a table established for a single material, such as the table for cartridge brass, some error is involved depending on composition and methods of processing. The conversion data of “Hardness Converter” is from the latest efficient version Chinese national standard, international standard, American standard: The equations given in Annex A10 were developed at the time the Leeb hardness test was invented see Appendix X2.

This is because conversions can be affected by several factors, including the material alloy, grain structure, heat treatment, etc. Most of the time, these methods are selective, involving destructive tests on samples.

Add Knoops hardness calculator; 3. These hardness conversion relationships are intended to apply particularly to the following: Generally, impact device types are optimized for certain application fields.

According to the dynamic Leeb principle, hardness value is derived from the energy loss of a defined impact body after impacting on a metal sample, similar to the Shore scleroscope. It is available for people to get more than 30 professional conversion tables. While in the traditional static tests the test force is applied uniformly with increasing magnitude, dynamic testing methods apply an gardness load.
