Hardness testing of the main use of Rockwell hardness tester, test HRA hardness value. PHR series portable Rockwell hardness tester is suitable for testing the hardness of cemented carbide. Instrument weight accuracy and desktop Rockwell hardness of the same, use and carry are very convenient.

Carbide is a kind of metal. The hardness test can reflect the difference of the mechanical properties of the cemented carbide material under different chemical composition, structure and heat treatment process conditions. Therefore, the hardness test is widely used in the testing of the cemented carbide performance, supervising the heat treatment The correctness of technology and new material research.

Features:

It belongs to a non-destructive test, the test method is relatively simple. Carbide hardness testing of its shape and size of the specimen adaptability, high test efficiency. In addition, there is a certain correspondence between the hardness of the cemented carbide material and other physical properties.

For example, the cemented carbide hardness test and the tensile test are basically the ability to detect the metal's resistance to plastic deformation, both of which are to a certain extent the similarities of metals. Therefore, the test results are completely comparable to each other. Tungsten carbide tensile test equipment is large, complex operation, to prepare samples, test efficiency is low,

For many metal materials, there is a conversion table for hardness and tensile tests. Therefore, when testing the mechanical properties of cemented carbide materials, more and more people use the hardness test, and the less the use of tensile test.

Tools:

Carbide hardness is generally measured with a Rockwell Hardness Tester HRA scale or Vickers hardness tester, in practice, people mainly use Rockwell hardness tester to test HRA hardness. PHR series portable Rockwell hardness tester is suitable for testing the hardness of cemented carbide. This instrument weighs only 0.7kg, the same accuracy and desktop Rockwell hardness tester.

In measuring the hardness of cemented carbide, the PHR series Portable Rockwell Hardness Tester produced by Star can test cemented carbide workpieces with thickness less than 50mm in diameter and can test cemented carbide workpieces with diameters as small as 2.0mm. 30mm tubular carbide workpiece. Can also be used at the production site, sales site or material warehouse.

This instrument is used to test hard alloy workpiece is simple, fast, nondestructive, batch finished or semi-finished carbide workpiece piece by piece hardness testing.
