The Rockwell test is a quick process, very cost-effective, and non-destructive test (causing only minor indentation on the specimen material). The Rockwell hardness test is a simple process that is why it can be performed by anyone .In the Rockwell hardness test, a differential-depth method, the residual depth of the indent made by the indenter, is measured.In contrast, the size of the indentation is measured in the Brinell, Vickers and Knoop optical test methods.. The deeper a defined indenter penetrates the surface of a specimen with a specified test load, the softer the material that is being tested.The Rockwell hardness test is an empirical indentation hardness test that can provide useful information about metallic materials. This information may correlate to tensile strength, wear resistance, ductility, and other physical characteristics of metallic materials, and may be useful in quality control and selection of materials. .
A Rockwell hardness tester. 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.
Rockwell hardness test measures the permanent depth of indentation on the material by applying a fixed load using an indenter. The smaller the indentation value, the harder is the material. The Rockwell hardness test follows the principle of the differential-depth method. Here, the indenter makes a residual depth called the indent and it is .ACKNOWLEDGMENTS Theauthorwouldliketothankthefollowingpersonsforsharingtheir experienceandprovidinginformationforthisGuide.Theirinputandreview .The minimum Test Specimen thickness is at least 10 times the indentation depth as per ASTM standard and the same is at least 8 times the indentation depth as per ISO standard. 5. Unit of Brinell Hardness . For the Rockwell Hardness Test, the Indenter is a Small Steel Ball (HRB) or a diamond cone (HRC)
