Introduction:

The Rockwell hardness test is one of several common indentation hardness tests used today. Rockwell hardness (HR) test When the measured sample is too small or the Brinell hardness (HB) is greater than 450, the Rockwell hardness measurement is used instead. The test method is to use a diamond cone with a vertex angle of 120 degrees or a steel ball with a diameter of 1.59mm / 3.18mm, and press it into the surface of the material under a certain load.

According to the hardness of the experimental materials, it can be divided into three different scales:

l  HRA is a kind of hardness obtained with 60Kg load and diamond cone indenter, which is used for extremely hard materials. For example: cemented carbide.

l  HRB is a hardness obtained with a 100Kg load and a hardened steel ball with a diameter of 1.58mm. It is used for materials with lower hardness. For example: annealed steel, cast iron, etc.

l  HRC is a hardness obtained with a 150Kg load and a diamond cone indenter, and is used for very hard materials. For example: quenched steel.
