How to Choose the Best and Cheapest rockwell hardness tester for HR-150A Testing in Chinese Manufacturing Companies When it comes to testing the hardness of materials in Chinese manufacturing companies, the HR-150A Rockwell Hardness Tester is a popular choice due to its accuracy and reliability. However, with so many options…
Choosing the appropriate rockwell hardness tester mainly depends on the hardness range and properties of the materials. Here are some reference suggestions: 1. For materials with high hardness, such as quenched steel, cemented carbide, etc., usually, the Rockwell hardness tester with the HRC scale is selected. Because the diamond cone…
The principle of the rockwell hardness tester is based on measuring the indentation depth to determine the hardness of the material. It applies the initial test force and the main test force successively. The role of the initial test force is to ensure good contact between the indenter and the…
A metal hardness tester is an instrument used to measure the hardness of metal materials. Hardness is an important indicator for measuring the ability of metal materials to resist local deformation, especially plastic deformation, indentation, or scratch. The metal hardness tester applies a certain pressure, impact force, or other forms…
