And the indentation of measured diameter can be converted into Brinell hardness value immediately. Our product is generally used to test large and medium-sized castings, forgings, steels, nonferrous metals as well as the semi-finished workpiece processed by quenching and tempering heat treatments, so hammer impact Brinell type is suitable for testing large forgings and castings with thick and big grains. Hammer Brinell hardness type’s testing range is from 100 to 350HBW when equipped with 7.26mm steel ball indenter while its testing range is from 350 to 650HBW when equipped with 4mm steel ball indenter. Compared with other impact types such as Shore type and Leeb type, Brinell hardness type’s result is influenced little by the outside factors, so its result is more stable and reliable. Additionally, Hammer Brinell type can leave a permanent Brinell hardness indentation which facilitates subsequent inspection and testing. In addition, Hammer Brinell hardness tester has a simple structure and cheap price and it is widely used in castings, forgings, rollings, heat treatments and other industries in China due to its simple structure and low price.

The SRBH-150 Portable Brinell Hardness Tester has two types of application: C clamp and hammer impact. It is capable of testing from small to very large specimens. It is especially suitable for assemblies inconvenient to be taken to the lab and not allowed to be cut. The test can be completed in any direction to test the hardness of upper, lower and lateral part of the specimen. The test head itself can be used as a hammer impact tester. It can perform the testing by touching one side of the work piece. Its accuracy is much higher than any other type hammer impact tester. According to the similarity principle of Brinell hardness testing, with testing force of 1580kg, indenter diameter of 7.26mm, then F/D2=30. The test condition of the HB tester is equivalent to the standard Brinell hardness test with 3000kgf and 10mm ball indenter. The SRBH-150 Portable Brinell Hardness Tester can be widely used to test the hardness of forgings, castings, steels, nonferrous metal and its alloy products, and to test the hardness of annealed, normalizing and tempered mechanical parts. 
Compared to the Leed type hardness tester, the Brinell tester has many advantages such as higher precision, fewer factors affecting accuracy and lower requirement on the surface roughness. The test result meets the requirements of most drawings without conversion and is more widely accepted in the international business.

SRBH-750 Magnetic Hydraulic Brinell Hardness Tester is consist of 2 magnetic chucks and 1 hydraulic Brinell hardness test head, which is applied to test body hardness of huge iron and steel work pieces on site. The core part is a small hydraulic system. The operator could load 750kg test force by using the handle. There is a release valve to control the test force. When the force reaches 750kg, the release valve will open and close and then the pressure will fall down. According to ASTM E110, it is kept loading to make the indicator of the dial point at 750kg test force for 3-4 times altogether. Thus it is equivalent to the test condition of Brinell hardness testing method to hold test force for 10-15 seconds. The test condition of the hardness tester is 5 diameter test ball and 750kg test force, so the values of F/D2=30, of which the test result equals to the test condition of 10mm test ball and 3,000kg test force.
