Hardness test according to Vickers

On metallic materials from very low to very high hardness, the Vickers hardness test is applicable. This hardness test is particularly suitable for very small and very hard samples.

Hardness test according to Rockwell

If the hardness of the metallic materials is within the following ranges, the Rockwell hardness test is applicable:

HRB: 20 bis 100HRB
HRF: 60 bis 100HRF
HRC: 20 bis 70HRC
HRA: 20 bis 88HRA
HRD: 40 bis 77HRD
HR15N: 70 bis 94HR15N
HR20N: 42 bis 86HR30N
HR45N: 20 bis 77HR45N

Hardness test according to Brinell

The hardness test according to Brinell is for metallic materials with the steel ball is determined as indenter only up to 450HB, the overlying hardness values were determined with the hard metal ball.
