A vickers hardness tester is an instrument used for measuring the hardness of materials. It uses a positive quadrangular pyramid diamond indenter with an included angle of 136° between the opposite faces to press into the surface of the specimen with a certain test force. After maintaining for a specified…
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…
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…
The key points for the daily maintenance of brinell hardness testers include the following aspects: 一、First, cleaning and protection Second, maintenance of measurement components Third, maintenance of the transmission mechanism Fourth, inspection of the electrical system Fifth, accuracy verification Sixth, data recording and management
