The Rockwell hardness test is one of the most basic and effective methods of hardness testing of different materials. It was invented by Stanley P. Rockwell in 1919 for determining the accurate and speedy measurement of hardness.
Hardness is the property of any material to resist deformations to its shape when it is subjected to an external force. Hardness testing is important for technical and engineering applications as it helps to determine the hardness and tensile strength of materials.
Rockwell hardness testing is the most commonly used method for assessing the hardness of specimens. Under this method, the hardness of the specimen is measured by assessing the depth of the indentation made by the indenter under the test load on the specimen surface.
Hardness tester is a device which is used to determine the hardness of a material. The hardness is determined by measuring the effect of a penetration on the surface of the specimen by a standard indenter.
