Tips to Use the Right Hardness Tester

When an engineer asks for a material with a specific hardness, it is important that that hardness level is achieved. If he or she demands Rockwell hardness numbers, it is crucial to use a Rockwell hardness tester. Substituting a different test can cause errors in…

How a Rockwell Hardness Tester Works

A Rockwell hardness tester is one of four common types of hardness testing (with Brinell, Vickers, and Leeb). It is most commonly used for metallic material. In order to successfully test metallic hardness with a Rockwell tester, the tester will feature either a diamond cone…

Early Metal Hardness Testing Methods

Metal hardness testing is used to determine the rigidity of a metallic substance. What constitutes hardness is somewhat vague, though a common definition of hardness characterizes how resistant the material is to warping and deformation. This testing process is crucial to the manufacturing industry, among…

History of the Rockwell Hardness Tester

The Rockwell hardness tester was invented by Stanley P. Rockwell when he was in need of a fast, non-destructive instrument to test hardness.  The only testers he had were Scleroscope, Vickers, and Brinell.  Each one of these tests had their own disadvantages.  The scleroscope was difficult to…
