1、 This steel anvil is an inspection tool used to calibrate the HT-450 and HT-550 high-strength rebound testers for concrete.

2、 The components of this steel anvil are made of steel and tool steel. The mating surface between the anvil core and the anvil body [Mohs taper 4] is ground, and the hardness of the anvil core surface is HRC58-62.

3、 This steel anvil is generally placed on a horizontal surface to calibrate the rebound instrument. The rebound instrument is tested vertically downwards to calibrate the calibration value of the rebound instrument.

The average calibrated rebound value of HT-450 concrete rebound tester in the impact test on the steel anvil is [N]=88 ± 2,

The average calibrated rebound value of HT-550 concrete rebound tester in the impact test on the steel anvil is [N]=83 ± 2

4、 As an inspection tool, after being subjected to 5000 to 8000 impact tests, the anvil core and anvil body can be ground flat on a flat surface before use. However, the hardness of the anvil core still needs to be maintained at HRC58-62, otherwise it cannot be used again.

5、 The steel anvil should be stored in a dry and dust-proof place to prevent rust and corrosion. The impact test surface should not be bumped randomly to check the standard condition of the tool.

6、 The weight of the steel anvil is 20KG, packaged in wooden boxes.
