The Rockwell hardness test machine uses three types of indents and six test forces. Depending on the material properties, hardness range, and size of the metal, there are a total of 15 scales available for selection, enabling the testing of almost all common metal materials from very soft to very hard. Its application scope is very broad. The Rockwell hardness tester has been widely used in industrial production and has become the main means for inspecting product quality and determining reasonable processing methods.
