A rockwell hardness tester for sale is a measuring instrument used to determine the stiffness or strength of metals. It works by using a harder tool—usually a diamond cone or steel ball—to penetrate the surface of the material being tested. The test results depend on the penetration depth of the tool and the impression left behind on the surface of the sample. Different test methods exist, each with advantages and disadvantages. This article will present the most common testing methods and their applications in a rockwell hardness tester for sale.
The most popular method for evaluating metal hardness is the Brinell test. The test uses a steel ball indenter to mark the surface of a sample, and then measures the diameter of the impression to determine the hardness value. The advantage of the Brinell method is that it can be applied to rough surfaces, which cannot be measured with other methods. It can also measure the hardness of soft materials. However, it can be less accurate than other methods, because the impression may not be completely distributed by the indenter and can be misleading if the surface of the sample is not well prepared.
Another popular method is the Rockwell test, which uses a diamond indenter to make an impression on a metal surface. The Rockwell scale indicates the hardness of the material, with a higher number indicating a harder material. The Rockwell test is suitable for all kinds of metals and can be used to evaluate metals in both their finished and unfinished states. The disadvantage of the Rockwell test is that it is more difficult to read than other methods.
Grainger offers a variety of Rockwell hardness testers for sale, each designed to measure specific types of metal alloys. Choose from a selection of analog and digital instruments, each designed to help you find the right hardness value for your application. You can also purchase a Leebs hardness tester, which uses sound waves to test the quality of metals. This non-destructive inspection technique is ideal for hard-to-test samples, such as small precision parts and thin materials.
