Details ： Product Introduction

Hammer Brinell hardness tester by hammering way to the steel ball to exert test force, the steel ball instantaneous pressed into the sample under the hammer force, leaving indentation on the sample, measured indentation diameter, look-up table to get Brinell hardness value.

The instrument is mainly composed of bracket, bar hardness block, steel ball and reading microscope, the test with a hammer hit the top of the bracket, the ball will be pressed into the sample and hardness block, in the sample and hardness block left indentation , The two indentation has a certain proportion of the relationship between the two indentation measured diameter, look-up table, you can get the sample Brinell hardness value.

This instrument is simple in structure, easy to carry, cheap in price, but because the test force is uncertain, the error is rather big, the accuracy of 8%, this instrument is currently generally used in the domestic casting, forging, rolling, heat treatment and other industries.

Application

Hammering Brinell hardness tester is mainly used to test a variety of large, assembled, non-cutting or inconvenient moving workpiece. Generally used for testing large and medium-sized castings, forgings, steel, non-ferrous metals and quenched and tempered semi-finished products.
