Among all the commonly used hardness methods, Rockwell hardness test is the only method that allows direct reading of the hardness value without the need for optical reading as per Vickers and Brinell methods.
Advantages:
It is the most rapid method and is fully automated. It has a rapid testing time. The direct hardness number is read out on the dial. This test can be used for a wide range of materials.
Disadvantages:
The main limitations are due to the fact that between maximum and minimum load there is only a 10:1 ratio. The possibility of errors due to shifting of samples under test loads during the test cycle. Quality of the indenter and surface has a strong influence on the test result.
