If the necessary precautions are not taken, metal hardness test blocks may suffer a problem which totally compromises their validity:
WHY DOES THIS HAPPEN?
Ferrous materials tend toward gradual corrosion due to their contact with oxygen and water. The higher the electrical conductivity of the aqueous solution is, the faster iron corrosion takes place. In the field of hardness testing, the main cause for rust forming is the sweating of the operator who handles metal test blocks.
THESE ARE OUR SUGGESTIONS TO PREVENT METAL HARDNESS TEST BLOCKS CORROSION:
Following these basic rules will help “extending test blocks lives” and will guarantee their effectiveness when verifying the accuracy of hardness values detected by the instrument.
