Carbide rods using rockwell hardness testing for a thermometer to measure the hardness. Portable rockwell thermometer weight is only 0.7 kg,which is very convenient to carry and use. Through hardness testing, we can get cemented carbide rods in different chemical composition, organizational structure and heat treatment process under the different mechanical properties. This is a kind of non destructive testing, and very easy to operate. This way of testing the test pressure is small, small indentation,measuring speed and high efficiency, thus can be directly applied to the measurement products.
Hardness test and tensile test has a certain similarity, both of which are used to test the metal plastic deformation resistance. Because of the tensile test is a destructive test, so the hardness testing than tensile test is more widely used.Carbide rods due to its high strength and high hardness of the demand is very big.Its intensity is much higher than all existing casting molten metal and alloy. It is hard for two to three times than steel, hard than iron or brass four to six times. Has all the characteristics of cemented carbide cemented carbide rods.
carbide rod hardness testing quality control
all raw material are tested in terms of density, hardness and T.R.S before use.
There are strict inspection on process and final products.
every batch of product can be traced.
