Hardness

Hardness testing is an evaluation of a given material’s resistance to deformation. It is commonly used to assess other qualities that are generally related to the hardness value (ductility, tensile strength, etc.).

​

Brinell Testing (HBW)

​

The OD of a tube or bar will have approximately 1/8″ of material ground down to create a flat spot. A test device will hydraulically apply 3000 kgf to a 10 mm tungsten carbide ball bearing. The indentation left behind will be measured with a microscope to the nearest .01 mm and converted to a Brinell value.

​

Rockwell Testing (HRB, HRC)

​

Rockwell indentations, in comparison to Brinell, are much smaller and hardly noticeable which makes it a great option for finished machine parts. Our tester is semi-permanently installed in our lab, meaning that we can only accommodate smaller pieces that can be hand carried.
