Introduction to the advantages and disadvantages of Brinell hardness
The Brinell hardness test has the advantages of strong representativeness, good data repeatability, and a certain conversion relationship with the strength. The disadvantage is that it is impossible to test harder materials; the indentation is large and it is not suitable for finished product inspection. Usually used to test the hardness of raw materials such as cast iron, non-ferrous metals, low-alloy steel and tempering parts.
