T able 2. Steel samples with their hardness in rockwell B and C scale. From the above hardness table it can be seen that all 10 sample hardness can not be measured with the same rockwell scale. So for comparison and plotting, all hardness value is converted to Rockwell B scale[2]. Converted value of hardness to the Rockwell B scale has been
how to use hardness tester
3.2 Conducting the Test. Positioning the Sample: Secure the material sample in the testing machine.; Selecting the Indenter: Choose the appropriate ball diameter based on the material hardness.; Applying the Load: Gradually apply the specified load using the machine.The load should be maintained for a predetermined dwell time, usually between 10 to 15 seconds.
4) For Rockwell hardness testing, no optical measurements are required; all readings are direct. There are two common methods applied to measure material hardness macroscopically: Rockwell and Brinell. Rockwell hardness differs from Brinell hardness testing in that the indentation size is measured in Brinell The Brinell hardness test ing uses indenters made of st eel to test materials with hardness values of up to 350 HB, or of hard metal (tungsten) to test materials with har dness values from 350 to .Standardization of Brinell Hardness Test Blocks Annex A4 1.3 This standard includes nonmandatory information in an appendix which relates to the Brinell hardness test: Table of Brinell Hardness Numbers Appendix X1 Examples of Procedures for Determining Brinell Hardness Uncertainty Appendix X2 1.4 At the time the Brinell hardness test was .
hardness test is a mechanical test for material properties which are used in engineering design, analysis of structures, and materials development. . Include the following information in the laboratory report. a. Compare results of the hardness tests for each metal to 'book' values from a source such as the ASM Metals Handbook. Comment on any .

Today, hardness testing is one of the most widely used methods in mechanical materials testing, especially for metals. On the one hand, this test method can be used to find qualitative relations to other material properties (e.g., strength, stiffness, density) or to the material behavior under certain stresses (e.g., abrasion .

In the retempering test Vickers hardness is measured before and after heat treatment. The reduction of hardness after retempering, if any, shall be less than 20 Vickers units. In the decarburization and carburization test hardness is tested to Vickers with a test force of 2.942 N (HV 0.3) on a longitudinal section through the thread axis. The .3.4 Vickers hardness test—an indentation hardness test using calibrated machines to force a square-based pyramidal diamond indenter having specified face angles, under a prede-termined force, into the surface of the material under test and to measure the diagonals of the resulting impression after removal of the force.
