Brinell hardness tester can be used to test castings, forgings, supplied steel, non-ferrous metals, and semi-finished steel workpieces that have undergone quenching and tempering heat treatment. This is * * kind of
The Brinell hardness tester is a portable instrument used in the workshop, with simple operation and easy portability. It can test large workpieces on site without sampling, and can achieve piece by piece testing of large workpieces.
The Brinell hardness tester is mainly used for hardness testing of uneven forged steel and cast iron. The Brinell hardness of forged steel and gray cast iron has a good correspondence with tensile testing. The Brinell hardness test can also be used for non-ferrous metals and soft steel, and small diameter ball indenters can be used to measure small-sized and thinner materials. Brinell hardness tester is commonly used for testing raw materials and semi-finished products. Due to the large indentation, it is generally not used for testing finished products.
The selection of Brinell hardness test conditions is similar to the selection of the scale in Rockwell hardness test. Brinell hardness test also encounters the problem of selecting test conditions, namely the test force F and the diameter D of the indenter ball. This choice is not arbitrary, but must follow certain rules and pay attention to the reasonable combination of test force and indenter ball diameter. It is slightly more complex to apply than the Rockwell hardness test.

indentation
Using a test force of 3000kg and a 10mm ball, the indentation produced can accurately reflect the true hardness of coarse-grained materials such as cast iron, cast steel, and forgings. The sexual indentation left after testing can be retested at any time.

True and accurate
According to the principle of real Brinell hardness test, it is the same as the principle of desktop Brinell hardness tester, and is not a conversion value with large distortion obtained by other portable instruments (such as Leeb hardness tester).

Testing**
The calibration accuracy of the test force is 0.5% of the load, and the hardness testing accuracy is the same as that of a desktop computer.

Any direction
No directional restrictions, can be used for measurements in any direction: including top, bottom, side, inverted, etc.
