The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1] There are different scales, denoted by a single letter, that use different loads or indenters. The hardness of steel depends on several factors, such as its composition, manufacturing, and heat-treating processes.The different hardness scales use different loads, different indentor shapes, and different measurements to obtain the hardness number. There are no straightforward formulae to establish relationships between the different scales, making .

Use these tables in selecting the scale that is appropriate for your application. Regular Rockwell Testing. In this test method, the minor (preload) is always 10 kgf. The major load may be any of the following loads: 60 kgf, 100 kgf, or 150 kgf.Vickers hardness test is a micro testing method used for some specified cases. 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.
1.3 Conversion Table 3 presents data on the relationship among Brinell hardness, Vickers hardness, Rockwell hardness, Rockwell superficial hardness, and Knoop hardness of nickel and high-nickel alloys (nickel content over 50 %). These hardness conversion relationships are intended to apply particularly to the following: nickel-aluminum-silicon .
a Brinell hardness values up to 450 HB w Brinell hardness values up to 450 HB were determined using a steel ball indenter, those above this value were determined with a hardmetal ball.. NOTE 1 Values in parentheses are those lying outside the defined range of the standard test method but which may used as estimates. NOTE 2 The value of the tension test are not based on method .
This results in 30 different Rockwell scales standardized according to ISO 6508 and ASTM E18 (e.g., A, B, C, 30N, 15T) or Rockwell test methods (e.g.: HRA, HRBW, HRC, HR30N, HR15TW), each covering different hardness ranges .obtained from computer-generated curves of actual test data.
