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...
Simplified operation of Rockwell hardness and depth-measuring Brinell hardness very simple with high efficiency. This instrument stores an accurate basic hardness, that is depth curve made from plenty hardness blocks. It also stores several Brinell curves of common materials. We can supply the service...
