The Bladder hardness meter is mainly used for the hardness measurement of cast iron, steel, non -ferrous metals, and soft alloy materials. The Belish hardness test is the largest test method in all hardness tests. It can reflect the comprehensive performance of the material. NoAffected by the micro -analysis of the sample tissue and uneven component, it is a high -precision hardness test method.
Principles of the Bladder hardness meter
Use a certain diameter steel ball or hard alloy ball to press the surface surface with the specified test force, remove the test force after maintaining the time, and measure the diameter of the indentation of the surface of the sample.The hardness value of the British is a business obtained from the splin spherical surface area with the test force.According to HBS (steel ball), the unit is N/MM2 (MPA).The hardness of Bobe is more accurate and reliable, but generally HBS is only suitable for metal materials below 450N/mm2 (MPA), which is not applicable to harder steel or thinner plates.In the steel pipe standard, the hardness of the British hardness is the most widely used. It often uses the diameter of the indentation to represent the hardness of the material, which is intuitive and convenient.

How to use the hardness meter in the BBC
First of all, you need to install the head and test platform of the Budi hardness meter. The head part of the equipment needs to be cleaned with acid -free gasoline to prevent rust. During the wiping processPress the head in the main axis, gently press the screws into the head of the head, and then put the sample to be determined smoothly and closely on the test platform of the instrument. By turning the hand wheelBetween the fixed rod, at this time, you can choose the test force and the test force to maintain the time. Before the selection, you need to turn on the power switch, and then press the time button to keep the time button.
