Introduction to Rockwell Hardness Tester
The Rockwell hardness tester is a widely used instrument for measuring the hardness of materials. It operates on the principle of indentation. A minor load is first applied to seat the indenter into the test material, and then a major load is added. The difference in depth of indentation before and after the application of the major load is used to determine the Rockwell hardness number. This method is quick, reliable, and can be applied to a variety of materials, including metals, plastics, and composites. It has become an essential tool in quality control, material research, and manufacturing processes across the globe.
