Sheet Metal Hardness Tester

The leeb rebound hardness test lrht is one of the four most used methods for testing metal hardness this portable method is mainly used for testing sufficiently large workpieces mainly above 1 kg.

Sheet metal hardness tester. The rh auto also serves as an excellent sheet metal tester. Material hardness testing determines a material s strength by measuring its resistance to penetration hardness test results can be extremely useful when selecting materials because the reported hardness value indicates how easily the material can be machined and how well it will wear. The leeb portable metal hardness tester pce 900 measures the hardness of nine different metals using the leeb rebound method. It is defined as the resistance to indentation and it is determined by measuring the permanent depth of the indentation.

Various retaining frames allows tests on different thicknesses. The hardness was obtained by applying 588n pressure at the diamond cone with 120 vertex angle for testing samples. Its light weight and small size is perfect for performing rockwell hardness tests on bulky and heavy sheet metal. Hardness testing rockwell brinell vickers hardness test more.

By attaching the tube test frame the rh auto becomes a metal tube tester. Sheet metal can be too thin and soft for testing with this method and it may not exceed the minimum thickness requirements which may also damage the test anvil. The hardness test is performed primarily for quality control in rolling and coating processes. This model can serve as a desktop hardness tester portable rockwell tester metal sheet tester metal tube tester or metal ball tester.

Citation needed it measures the coefficient of restitution it is a form of nondestructive testing. Hardness is a characteristic of a material not a fundamental physical property. Hardness testing on thin sheets and coated metal sheets are performed to determine the surface hardness of the metal and coating. Take a look at their rh auto series rockwell hardness tester a modular tester that is adaptable to many different types of applications.

This means that with the hardness tester a firing pin bounces on a metallic surface and the intensity of the rebound is used as an indicator of the material hardness. Testing the hardness of sheet metal can become difficult with the rockwell method. It is suitable for measuring hard metal such as tempered steel and hardened steel.
