chuanbai 150J 300J 450J Dial Display Manual Pendulum Metal Charpy Impact Testing Machine/Impact Tester

The JB-300B impact tester is used to determine the resistance of metal materials to impact under dynamic load, and to judge the quality of the material under dynamic load.

This machine is a semi-automatic control testing machine with simple operation, high working efficiency, electric control of swing, impact and swing. It can automatically use the remaining energy after punching the sample to prepare for the next test, especially suitable for continuous operation. Impact testing laboratory and a large number of metallurgical, mechanical manufacturing industries for impact testing.

This series of impact testing machine is used to test the impact resistance of metal materials under dynami- cload. It is a necessary testing instrument for metallurgy, mechanical manufacturing and other units.It is also an indispensable testing instrument for scientific research institutions to conduct research on new materials.

Charpy impact test is a test material notch toughness test, the preparation of the standard is 55 mm long and 10 mm wide and thickness less than 10 mm sample, in a surface processing a 2 mm deep u-shaped or v-notch, control the pendulum is under the impact in setting height relative surface notch, pendulum thrust sample after the height of the swing-up is a measure of the energy absorption after blunt crack sample, which can measure the absorption of energy in the sample fracture, in order to get the notch toughness of the material was tested.Typically, three samples are tested at any one temperature and the results averaged.Charpy tests can be performed on ASTM E23 and ISO 148 at various test temperatures.
