Measuring range of portable hardness tester

Let's take a look at the small hardness of the portable hardness tester.

According to the principle of Richter, as long as the material has a certain rigidity and can form a rebound, the accurate hardness of the Richter scale can be measured. However, many materials have no corresponding conversion relationship with the hardness of other systems, so the Leeb hardness tester is currently only installed. Conversion table of nine materials.

The specific materials are as follows: steel and cast steel, alloy tool steel, gray cast iron, ductile iron, cast aluminum alloy, copper-zinc alloy, copper-tin alloy, pure copper, stainless copper. For samples of special materials, the user can use the fitting curve software provided by the company to make a special conversion table.

In actual production, the metal materials used are various. Because the Leeb hardness tester is sensitive to the processing method of the material and the alloying element composition of the material, the hardness conversion table stored in the Leeb hardness tester chip cannot meet the needs of the user. In the test, the user can use the fitting software to make his own special hardness conversion table.

The test principle, symbols, samples, test instruments, tests, test results and test reports of the metal Leeb hardness test are specified in the Leeb hardness tester. The main features of the Leeb hardness tester are: the main technical specifications of the test specimen are specified, including: surface roughness, weight, *small thickness, *small surface hardened layer depth and *small radius of curvature. A test method for performing a Richardis test on a sample. The conversion table for the hardness and other hardness of various materials is given. The materials include: carbon steel, cast steel, cast iron, low alloy steel, cast aluminum, copper-zinc alloy, copper-tin alloy, pure copper.
