Hardness is not an elementary physical property. It is more of a characteristic of a material. Hardness is defined as an object’s ability to resist indentation. Its hardness is then measured by the irreversible depth of the indentation. When utilizing a load and a certain indenter, one usually looks out for the size of the indentation. The smaller the indentation, the harder that part will be.
With that in mind, hardness testing is used for two general characterizations, which are functionality and material characteristics. You can use hardness testing for predicting tensile strength, testing wear resistance, testing resistance to impact, testing hardenability, and more. Before a test is conducted, scale, thickness, sample size, material, etc., are some of the factors that will be considered prior to selecting the hardness testing method. In this product spotlight, you will find out more about an excellent hardness testing tool that can make this task easier. Introducing the Phase II PHT-5100 Digital Barcol Impressor Hardness Tester.
