Hardness requirements: HS<100, HB<500, HRC<70, HV<1300, HRA(80~88), HRB(85~95), HRC(20~70)

In Rockwell hardness, A, B, and C in HRA, HRB, and HRC are three different standards, called scale A, scale B, and scale C.

The Rockwell hardness test is one of several common indentation hardness tests in use today. The initial pressure of the three scales is 98.07N (10kgf), and the hardness value is calculated according to the indentation depth. Ruler A uses a diamond indenter, and then pressurizes to 588.4N (60kgf); ruler B uses a steel ball with a diameter of 1.588mm (1/16 inch) as the indenter, and then pressurizes to 980.7N (100kgf); and ruler C uses the same diamond as ruler A as the indenter, but the force after compression is 1471N (150kgf). Therefore, scale B is relatively soft. Practice has proved that there is an approximate correspondence between the hardness value and the strength value of various hardness values of metal materials. Because the hardness value is determined by the initial plastic deformation resistance and continuous plastic deformation resistance, the higher the material strength, the higher the plastic deformation resistance and the higher the hardness value. However, the conversion relationship of various materials is not consistent.
