THE BRINELL HARDNESS TEST
What is the Brinell hardness test and how does it work?
The Brinell hardness test is the most used hardness testing method in foundries, forges, heat treatments, steel shops, and castings. Thanks to the wide range of testing loads and different sizes of ball indenters, the Brinell measurement can test the hardness on all metals from hard steel, Nickel alloys, Titanium alloys, and cast iron to aluminum, copper, and light metals. The most used Brinell scale to test hard metals is HBW10/3000 (HB30) and the one to test soft metals is HBW10/1000 or HBW 2.5/62.5 (HB10).
The Brinell testing method is an empirical indentation hardness test that can provide useful information about metallic materials. This information may correlate to tensile strength, wear resistance, ductility, and other physical characteristics of metallic materials, and may be useful in quality control and selection of materials.
PRINCIPLE OF BRINELL HARDNESS TEST METHOD
An indentation hardness test using a verified machine to force an indenter (tungsten carbide ball with diameter), under specified conditions, into the surface of the material under test. The diameter of the resulting indentation is measured after removal of the force.
The 2 steps for the principle of the Brinell test method
The general principle of the Brinell indentation hardness test consists of two steps:
Step 1 – The indenter is brought into contact with the test specimen in a direction perpendicular to the surface, and the test force is applied (Apply the test force within 1 to 8 s). The test force is held for a specified dwell time and then removed (Maintain the fully applied test force for 10 s to 15 s).
Step 2 – The diameter of the indentation is measured in at least two directions perpendicular to each other. The Brinell hardness value is derived from the mean of the diameter measurements.
