3 requirements for materials testing machines

DifferentMaterial testing machineBy conducting different tests on different materials, the technical engineer of Jinan Hengsi Shanda Instrument Co., Ltd. has given a detailed understanding of the material testing process of the material testing machine.

1. For general metal and non-metallic specimens, the jaws of the fixture are in direct contact with the specimens. Generally, high-quality alloy structural steel, alloy high-carbon steel or low-carbon alloy steel, cold-work mold steel, etc. are used to increase their strength and wear resistance through appropriate heat treatment processes. Sometimes special steel is also installed at the jaws, or gold steel sand is sprayed on the surface of the jaws.

2. For some fixtures with small test force, the surfaces in contact with the sample are used to use soft rubber leather.

3. Generally, high-quality medium-carbon steel and alloy structural steel are used to increase their mechanical properties through appropriate heat treatment processes. Sometimes, non-ferrous metals such as aluminum alloys and special metals are used in order to reduce weight. Sometimes cast structure cast steel, cast aluminum, etc. are also used.
