What is a Brinell hardness meter and will it be used in those tests?

Brinell hardness meterIt can be used to test castings, forgings, steel in supply status, non-ferrous metals and semi-finished steel workpieces that have been tempered and heat treated. This is a portable instrument that can be used in the workshop. It is simple to operate and easy to carry. It can test large workpieces on site without having to take samples, and can realize piece-by-piece inspection of large workpieces.

Brinell hardness meterIt is mainly used for hardness testing of forged steel and cast iron with uneven tissues. The Brinell hardness of forged steel and gray cast iron has a good correspondence with tensile test. Brinell hardness tests can also be used in nonferrous metals and mild steels, and small diameter ball indenters can measure small sizes and thinner materials.Brinell hardness meterIt is mostly used for the detection of raw materials and semi-finished products. Due to the large indentation, it is generally not used for the detection of finished products.

The selection of Brinell hardness test conditions is just like the selection of the scale of the Rockwell hardness test, the Brinell hardness test also encounters the selection of test conditions, namely the selection of test force F and the diameter of the header ball D. This choice is not arbitrary, but must follow certain rules, and pay attention to the reasonable combination of test force and header diameter, which is slightly more complicated than Rockwell hardness test.

Brinell hardness meterThe working principle is to press the steel ball of a certain diameter into the sample surface at a certain speed under the action of a certain test force, and remove the test force after the specified test force is maintained. The Brinell hardness value of the metal is represented by the average pressure on the spherical surface area of ​​the indentation sample.
