Product Description

SHB-3000B uses 20X Brinell measuring microscope to measure the diameter of indentation, then the operator traces the Brinell hardness table to get the testing result.

The Brinell hardness test method consists of indenting the test material with a 10 mm diameter hardenedcarbide ball subjected to a load of 3000 kg. For softer materials the load can be reduced to 1500 kg or 500kg to avoid excessive indentation.
The full load is normally applied for 10 to 15 seconds in the case of iron and steel and for at least 30 seconds in the case of other metals. The diameter of the indentation left in the test material is measured with alow powered microscope. The Brinell harness number is calculated by dividing the load applied by the surface area of the indentation.
 
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 theother 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 macro-hardness of a material, particularly those materials with heterogeneous structures.
