The Steel Anvil is made of the high quality steel and high quality tool steel.

Pls set in the horizontal plane calibrating test instrument. The test hammer test on the steel anvil vertically down to calibrate rate fixed value. The average rate fixed value of concrete test hammer is【N】=80+2. The average rate fixed value of Mortar test hammer is【N】=74+2.

As calibration tool, when it is tested 5000-8000 times, it could put anvil core and anvil body grinding flat on the above plane. But the anvil core hardness should keep in HRC58-62.
