LAB 1 – “Hardness Test”
Hardness Test
Hardness Results
(include appropriate
hardness label with
number, i.e., 38.2
HRE)
Aluminum, HB

Aluminum, HRK
78.5 HRK
Aluminum, HRB
60.8 HRB
Steel, HB

A. What were the indentor-load combinations used for each of the four Rockwell
tests. Include the scale letter with its combination.
HRK uses a 150 kg load and a ⅛” diameter steel sphere. HRB uses a 100 kg load with
a 1/16” diameter steel sphere as well. HRG used a 150 kg load as well with a 1/16”
diameter steel sphere. HRA use don;y a 60 kg load with a 120 degree diamond brale.
B. Why are so many different load and indentor combinations available for hardness
testing?
Different materials require different indentor geometries and loads to accurately display a
detent used for hardness testing. Some softer materials might become impacted too much from
higher loads.
C. Explain why the HRK and HRB values for the aluminum sample are different
from each other. Which one is higher/lower? Why?
They are different because the loads for the two tests are different from one another
and the diameter of the steel sphere is also different.
