Sheet Metal Hardness Tester

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.

Sheet metal hardness tester.

The hardness was obtained by applying 588n pressure at the diamond cone with 120 vertex angle for testing samples. The hardness test is performed primarily for quality control in rolling and coating processes. Zwickroell s bup sheet metal testing machines test these properties with drawing forces up to 1 000 kn. The leeb portable metal hardness tester pce 900 measures the hardness of nine different metals using the leeb rebound method.

Take a look at their rh auto series rockwell hardness tester a modular tester that is adaptable to many different types of applications. Hardness testing rockwell brinell vickers hardness test more. It is suitable for measuring hard metal such as tempered steel and hardened steel. 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. It is defined as the resistance to indentation and it is determined by measuring the permanent depth of the indentation. This model can serve as a desktop hardness tester portable rockwell tester metal sheet tester metal tube tester or metal ball tester. Hardness testing on thin sheets and coated metal sheets are performed to determine the surface hardness of the metal and coating.

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. Citation needed it measures the coefficient of restitution it is a form of nondestructive testing. By attaching the tube test frame the rh auto becomes a metal tube tester. Various retaining frames allows tests on different thicknesses.

The rh auto also serves as an excellent sheet metal 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. 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.
