The Rockwell hardness test provides the fastest and most accurate way to test the hardness of a material and takes place over three stages. In stage one, a load of force is applied to the material being tested for a short period of time, commonly using a diamond or ball indenter to apply the force. In stage two, the force being applied is increased and is called the major load. In stage three, the major load is removed from the material being tested and the original smaller load of force is applied once again. After this process is complete, the resulting indentation is measured and used to calculate the difference between the final and original indentation depths. The force applied using the indenting tool typically ranges between 15kgf and 3000kgf. There are several different Rockwell hardness scales, each identified by the use of a letter including A, B, C, D, E, F, G, H, and K.

At NextGen, our NG-RockGen Analogue Rockwell Hardness Tester can test the following 6 superficial scales: HR15N, HR30N, HR45N, HR15T, HR30Tand HR45T.
