The Rockwell hardness tester is the first choice for the hardness testing of high-quality alloys to test the HRA hardness value. The PHR series portable Rockwell hardness tester is very suitable for testing the hardness of cemented carbide die tools. The weight accuracy of the instrument is the same as that of the desktop Rockwell hardness tester, and it is very convenient to use and carry.
Cemented carbide mold is a kind of metal. The hardness test can reflect the difference in mechanical function of cemented carbide mold material under different chemical composition, arrangement structure and heat treatment process conditions. Therefore, hardness test is widely used in the inspection of cemented carbide mold function. , Supervise the correctness of the heat treatment process and the research of new materials.
Features:
It is a non-destructive experiment, and the experimental method is relatively simple. The hardness test of the cemented carbide mold has a strong adaptability to the shape and size of the test piece, and the experimental power is high. In addition, there is a certain correspondence between the hardness of the cemented carbide mold data and other physical properties.
For example, the hardness test of cemented carbide mold and the tensile test are basically testing the ability of metal to resist plastic deformation, and these two tests are testing the similar characteristics of metal to some extent. Therefore, the test results are completely comparable to each other. The tensile test equipment of cemented carbide die is huge, the operation is complicated, the sample needs to be prepared, and the test power is low.
For many metal materials, there is a conversion table for hardness test and tensile test. Therefore, when cemented carbide mold manufacturers are testing the mechanical functions of cemented carbide mold materials, more and more hardness tests are used, and tensile tests are rarely used.
Hard alloy mold hardness is generally tested with Rockwell hardness tester HRA scale or Vickers hardness tester. In practice, people first choose Rockwell hardness tester to test HRA hardness. The PHR series portable Rockwell hardness tester is very suitable for testing the hardness of cemented carbide die tools. The weight of this instrument is only 0.7kg, and its accuracy is the same as that of a desktop Rockwell hardness tester.
When measuring the hardness of cemented carbide die tools, the PHR series portable Rockwell hardness tester produced by the company can test cemented carbide mold workpieces with a thickness or diameter of less than 50mm, and can test cemented carbide mold workpieces with a diameter as small as 2.0mm. Tubular hard alloy workpiece with inner diameter less than 30mm. It can also be used at the production site, the sales site or the data warehouse.
This kind of instrument is used to test cemented carbide mold workpieces in a simple, fast, and non-destructive way. It can test the hardness of batches of products or semi-finished carbide workpieces piece by piece.
