Conversion tables
Hardness conversion table for steel
In the data charts or their introductions, the hardnessess of the individual versions and dimensions of Seeger rings are given in Rockwell C (HRC) and Vickers (HV). Vickers hardness can be measured on all thicknesses at an appropriate load. Due to the high load of 150 kg, Rockwell measurement can only be applied to thicknesses in excess of 1,1 mm. Vickers hardness must be measured on smaller thicknesses. Converting hardness values always involves inaccuracies. If ever possible, conversion should be avoided. However, conversion cannot always be avoided completely. This applies above all to conversion from hardness values to strength and vice versa.
