Audited Supplier SHB3000E adopts the load cell to replace the traditional weight, this innovative design makes the instrument more accurate.
SHB3000E selection of testing force and dwell time is controlled and monitored on the front panel, it is automatic during the process of loading, dwell and unloading.
SHB3000E uses 20x Brinell measuring microscope to measure the diameter of indentation, then the operator traces the Brinell hardness table to get the testing result.
Brinell Microscope
The diameter of the impression is the average of two readings at right angles and the use of a Brinell hardness number table can simplify the determination of the Brinell hardness.
A well structured Brinell hardness number reveals the test conditions, and looks like this, "75 HB 10/500/30" which means that a Brinell Hardness of 75 was obtained using a 10mm diameter hardened steel with a 500 kilogram load applied for a period of 30 seconds.
On tests of extremely hard metals a tungsten carbide ball is substituted for the steel ball. Compared to the other hardness test methods, the Brinell ball makes the deepest and widest indentation, so the test averages the hardness over a wider amount of material, which will more accurately account for multiple grain structures and any irregularities in the uniformity of the material.
This method is the best for achieving the bulk or macrohardness of a material, particularly those materials with heterogeneous structures.
