The Rockwell hardness test uses three kinds of indenters and six kinds of test forces. According to the material of the metal material, the hardness range and the size, there are 15 rulers to choose from. It can test almost all common metal materials from very soft to very hard. The scope of application is very broad.

Rockwell hardness tester has been widely used in industrial production, and it has become the main means to verify product quality and determine reasonable processing technology. It can test various black and non-ferrous metals and test the hardness of hardened steel, tempered steel, annealed steel, case hardened steel, various thickness plates, hard alloy materials, powder metallurgy materials, and thermal spray coatings.
