www.csun.eduMeasurement of Hardness Throughout this experiment, hardness measurements will be made using a Rockwell hardness tester. A 1/16" steel ball indentor with either a 60 or 100 kg load corresponds to the Rockwell F or Rockwell B scales. Hardness value may be calculated from the load applied divided by the surface area of the indentation.
