A rockwell hardness tester for sale is a vital piece of testing equipment in any metalworking shop. They are designed to test the hardness of a variety of materials using a number of different methods and scales. From bench-top models that use standard loading techniques to portable ultrasound models for non-destructive evaluations on the go, there are a wide range of options for all types of materials.
A traditional Rockwell hardness tester uses a diamond cone or a penetrating steel ball to test the hardness of the material. The depth of the impression created on the surface of the sample is used to calculate the hardness. While this method is relatively easy to use, it does not work well for soft metals and it can only be used on flat surfaces. The Brinell method of testing is more reliable because it uses a spherical indenter that distributes the load evenly over the entire surface of the sample. It can also be used on a wide range of metals, but the impression left on the surface of the sample must be smooth and free of imperfections to be accurate.
Grainger stocks many different models of Rockwell, Brinell and Vickers hardness testers for measuring the hardness of a variety of metal alloys. You can choose from a basic analog or digital model for measuring Rockwell Regular and Superficial scales, an advanced Universal hardness tester range that tests all Rockwell scales, as well as Brinell and Vickers, and a series of automatic in-line testers for high volume testing.
The 900-332 Rockwell hardness tester from Phase II is a state-of-the-art unit that offers unparalleled performance and dynamic precision. The system is easy to operate, meets all the requirements of ASTM E-18 Rockwell hardness standards and delivers repeatable results in a variety of different hardness scales. It is suitable for a variety of environments, including heat treat facilities, tool rooms and inspection labs.
