Rockwell Hardness Test | GRHardnessTester.comIf you work in any industry that manipulates plastic or metal, or with plasma coatings, then you are probably already comfortable with the findings delivered by the Rockwell hardness test. You may be familiar with the various ratings delivered by the test. Do you know, however, how those measurements are obtained? The portable Rockwell hardness tester has been a boon to professionals for many years. Here is the reason why:

Using indentations left in the material by a diamond or tungsten carbide cone, measurements are taken that provide information about the hardness of the material, its level of resistance, and its tensile strength. Replacing several older forms of testing, the Rockwell hardness test is now the most common testing method. Professionals in industries such as education, research, and construction rely on these measurements. Because of its wide-spread use, the need for a portable tester is clear.

For those who have not worked with the tester before, a quick introduction may be in order. An indenter, either a cone, ball, or brale, is used to leave an impression in the test material – both with a major load and a minor load. With the first two marks used as a control, the amount of pressure used to create the indentation is gradually decreased until the original amount of load has been reached. A hardness rating can then be figured using the difference between the indentations. The portable Rockwell hardness tester allows professionals to take the measurements they need no matter where they are situated.

When you require testing of materials, such as plasma coatings, bearing metals, cemented carbides, and malleable iron, among others, a portable piece of machinery can provide you with a huge advantage. The accurate and versatile portable Rockwell hardness tester allows you to obtain the measurements you need within just a few minutes and just one push of a button. The complicated Scleroscope test and the time-consuming Vickers test have been successfully replaced by this one very convenient tool. When you need to know how hard or how strong your material is, turn to Rockwell’s convenient hardness testing method.
