There are thirty Rockwell scales for testing steel, brass and other metals. A scale for testing is selected on the basis of different factors such as type of material, specimen thickness and material homogeneity...
Rockwell a scale (HRA):Used for measuring the hardness of thin steel and non-ferrous materials. The indenter is a diamond cone. The Rockwell hardness value is expressed as a combination of a hardness scale symbol and a hardness number. For example, HRC 55 indicates a hardness of 55 on the...

hardening steel after carbonized, hardened thin steel strip and plate, etc.For materials HRC > 67, it is more likely to damage the diamond indenter if we use 1471 test force. For those materials, we had better choose HRC hardness scale which has small test force and indentation.● HRB is...
