Brinell Hardness Test

Name:
Brinell Hardness Test
Detailed information:
The standard method of measuring the hardness of metals. The smooth surface of the metal is dented by a steel ball under force. The standard load and time are 500 kg for 60 seconds for soft metals and 3000 kg for 30 seconds for steel and other hard metals. The size (diameter) of the resulting dent is measured, and the hardness determined from a chart or formula.
