Brinell hardness tester uses the old-fashioned method of hardness testing today, and it is an incredible invention of Sweden by Dr Johan August Brinell, hence named after him. If an object is too complex for Rockwell and Vickers testing, it is best to use the Brinell hardness tester to determine its forgings and casting. Brinell hardness tester encompasses twenty-five different ball combinations of testing, making it suitable across almost all metals.
Most industrial companies use Brinell hardness tester for quality purposes seeing that they can withstand harsh environments.
Steps to Follow for Brinell Hardness Test
Use an indenter, apply the force through the indenter perpendicularly to the material being tested for a specified amount of time.
After completing step one, move to step two, where you will measure the diameter of the final indentation in at best two different directions perpendicularly to each other.
Use the mathematical formulae or a chart for this specific testing to determine the hardness/value of the said material.

Brinell hardness testers are helpful for coarse structured materials; this is to say that materials with very rough surfaces make them impossible to test using other forms of hardness testers like Vickers or Rockwell.
