Sheet Metal Hardness Tester

Hardness testing on thin sheets and coated metal sheets are performed to determine the surface hardness of the metal and coating.

Sheet metal hardness tester.

It is defined as the resistance to indentation and it is determined by measuring the permanent depth of the indentation. 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. Mainly used for metal materials the method is to press the specified indenter into the material under test with a certain load and compare the softness and hardness of the material under test with the local plastic deformation of the material surface.

Various retaining frames allows tests on different thicknesses. Zwickroell s bup sheet metal testing machines test these properties with drawing forces up to 1 000 kn. Hardness testing rockwell brinell vickers hardness test more. This model can serve as a desktop hardness tester portable rockwell tester metal sheet tester metal tube tester or metal ball tester.

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. Its light weight and small size is perfect for performing rockwell hardness tests on bulky and heavy sheet metal. Hardness is a characteristic of a material not a fundamental physical property. 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.

It is suitable for measuring hard metal such as tempered steel and hardened steel. The leeb portable metal hardness tester pce 900 measures the hardness of nine different metals using the leeb rebound method. 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.

In such situations. Take a look at their rh auto series rockwell hardness tester a modular tester that is adaptable to many different types of applications. The hardness was obtained by applying 588n pressure at the diamond cone with 120 vertex angle for testing samples.
