Hardness Testing
Standard Mechanics performs many different hardness testing services such as Rockwell, Brinell, Vickers, Knoop, and Shore. If you are interested in dynamic hardness properties, feel free to reach out, so we can discuss how we can perform the hardness test at the speed you need.
Hardness Testing Data
Hardness testing provides a single value that can be used to compare the hardness of different materials. This value is related to the force applied through an indenter on the specimen and the size of indentation left. The harder the object, the smaller the indentation. Hardness testing is non-destructive. This makes it an attractive option for quality control of components since the sample is not failed during the test. The hardness value obtained can be generally related to other mechanical properties such as yield strength that are found through destructive tests such as tensile tests.
There are many different hardness testing standards. The major difference between them is the indenter tip used. Even within a single standard, like in Rockwell testing, there can be several different tip geometries available depending on the type of material being used. Tips can range from a diamond point to a large round ball. In standards that have different tips that can be used, a letter indicating the tip geometry and the scale is used in reporting. Generally there is not a conversion factor to change a hardness value from one scale or standard to another, but there are hardness conversion charts that can approximate a conversion.
