SUMMARY
The discussion focuses on determining the K value for scaling measurements in Rockwell hardness testing, specifically using the Rockwell/Vickers machine. The Rockwell number is calculated using the formula N - h/S, where h is the permanent indentation depth in mm, and N and S are constants specific to the test type. For Rockwell B (HRB), the constants are N=130 and S=0.002 with a 100kg test load, while for Rockwell C (HRC), they are N=100 and S=0.002 with a 150kg test load. The units in question are confirmed not to be in kilograms.
