Tungsten carbide rod hardness test mainly adopts Rockwell hardness tester to test HRA hardness level. This is a kind of non-destructive test, and is relatively easy to operate. This kind of detection method has small testing force and little indentation, high measuring speed and high efficiency; therefore, it can be directly used to test finished products.
Hardness test has certain similarities with tensile test, both of which are used to test the resistance capability of metals to plastic deformation. Because tensile test is a kind of destructive test, so hardness test is adopted more frequently than tensile test.
