Brinell Hardness Test. The Brinell hardness test entails measuring the diameter of indentation caused by a constant concentrated force applied by a steel or carbide spherical indenter on a test specimen. The steel ball indenter is first placed in contact with the material before a constant force is applied and maintained for a 10 to 15 second duration, known as the .The Vickers hardness test is often regarded as easier to use than other hardness tests: The process can be performed on a universal or micro hardness tester; the required calculations are independent of the size of the indenter; and the same indenter (a pyramidal diamond) can be used for all materials, irrespective of hardness.Learn all you need to know about Rockwell hardness testing – including test definitions, test calculations and insight into Rockwell hardness testing machines and HRC hardness testers – with knowledge and expertise from Struers, the world’s leading materialographic and metallographic experts.Brinell [HB] is one of the most common units used for listing the hardness of steel materials. The test is done with a 10 mm steel ball pressed with 3000 Kgf (6,614 Lbf). Common values for machined materials range from 100 HB for very soft materials up to 650 HB for heat-treated steels.. The advantage of Brinell [HB] over Rockwell [HRC/HRB], is that the whole range is .
