The test is done with a 10 mm steel ball pressed with 3000 Kgf (6,614 Lbf). Common values for machined materials range from 100 HB for very soft materials up to 650 HB for heat-treated steels.. The advantage of Brinell [HB] over Rockwell [HRC/HRB], is that the whole range is .
Sometimes it becomes necessary to change the hardness value from one scale to another. Here we compare the Vickers hardness method with the Rockwell method and their conversion charts. . (HR) and has four types: HRC, HRA, HRB, and HRD. The Rockwell hardness test is performed by measuring the depth of indenter caused by throwing the heavy load .
The Rockwell hardness test method, as defined in ASTM E-18, is the most commonly used hardness test method. You should obtain a copy of this standard, read and understand the standard completely before attempting a Rockwell test. . The Rockwell hardness value is derived from the difference in the baseline and final depth measurements. This .
3. Rockwell hardness uses the depth of indentation plastic deformation to determine the hardness value index. A unit of hardness is 0.002 millimeters. When HB>450 or the specimen is too small, the Brinell hardness test cannot be used and the Rockwell hardness measurement is adopted instead.

Rockwell hardness does have a relationship to tensile strength in some structural alloys, such as steel and aluminum. The Rockwell hardness test involves making an indentation on the test material. The indenter is either a conical diamond or a steel ball. . For instance, a hardness value of 80 on the Rockwell A scale is denoted as 80 HRA. For example, in different aluminum alloys such as 2A12-T4/T351, 5A06-H112, 6A02-T4/T6, etc., the hardness values will vary. Also, the measurement of hardness is related to the test methods, such as Rockwell, Brinell and Vickers hardness. In addition, there are H12 and H24 hardness aluminum alloys. H12 hardness aluminum plate has good deep . The Rockwell Hardness test is a widely used method to determine the hardness of metallic materials, thanks to its simplicity and quickness. . For instance, the HRB scale is employed for testing soft steels, aluminium, and brass, and involves applying minor loads of 10kgf and major loads of 100kgf.
