How much do you know about the testing range of Rockwell hardness testers?

1. The Rockwell hardness test uses 3 types of indenters and 6 types of test forces. Depending on the range and size of metal materials and different scales of hardness, there are various choices.
2. It can test metal materials from very soft to very hard, including almost all common metal materials, and its application range is very broad.
3. Rockwell hardness testers have been widely applied in industrial production and have become a primary means of detecting product quality and determining reasonable processing techniques.
4. It can be used to test various ferrous and non-ferrous metals, and test the hardness of quenched steel, quenched and tempered steel, annealed steel, surface-hardened steel, plates, cemented carbide materials, powder metallurgy materials, and thermal spray coatings.
5. The Rockwell superficial hardness tester is used to test the hardness of plates, thin-walled tubes, surface-hardened steel, and small parts.
