Rockwell Hardness Test




Taiwan Nakazawa Rockwell Hardness Test 


Model
FR-X3


Measuring range


1. Test load (kgf): 15, 30, 45, 60, 100, 150
2. Load holding time: 5 ~ 99 seconds


Measurement items
sample hardness and adhesion



In the Rockwell hardness test, different indenters and different test loads are used, corresponding to different scales of Rockwell hardness. The Rockwell hardness machine uses a 120° diamond cone indenter to press into the surface of the material with a certain load to produce an indentation, and the depth of the indentation is converted to represent the Rockwell hardness value of the material.
