Shear pin Brinell hardness testerGood repeatability, high, tested by the China Institute of Metrology, with an error of no more than 2-3% HB, in compliance with the Chinese standard GB/T231, and the same as the desktop Brinell hardness tester. Easy to operate, convenient, and fast. The static force application method is used to test small and medium-sized parts, while the hammering force application method is used to test large parts. Each experiment only consumes one cheap shear pin, resulting in lower testing costs. Can replace the low Leeb hardness tester and old-fashioned hammer Brinell hardness tester.

Technical parameters of hammer Brinell hardness tester:
Test force: 1580kg
Test force error:<0.5%
Pressure head: 7.26mm steel spherical pressure head, testing range 100~350HBW
4.0mm hard alloy spherical indenter, testing range
350~650HBW
Indication error: Static error:< 2-3% HB, in compliance with standard GB/T231
Hammer strike error:< 5%HB
Repetitive error: Static error:< 2-3% HB, in compliance with standard GB/T231
Hammer strike error:< 5%HB
Test range: 100~650HBW
Application scope: castings, forgings, steel, bronze, heat-treated parts

Application Description:
﹡The static hardness tester using a C-frame is relatively high, and as long as the workpiece size is appropriate, it should be preferred.
﹡When using a hammer type hardness tester, regular comparative tests should be conducted with a desktop Brinell hardness tester to verify
The accuracy of the experimental results. The non desktop Brinell hardness tester can be replaced by a C-type static hardness tester.
