Hardness tester
Hardness is a property of a material that characterizes the resistance of local plastic
deformation that occurs when a more solid body (indenter) is introduced into this material.

Hardness is a property of a material that characterizes the resistance of local plastic
deformation that occurs when a more solid body (indenter) is introduced into this material.
     Hardness is measured by hardness testers that are classified by standards (ISO and ASTM)
according to methods for determining hardness readings:
      1. ROCKWELL HARDNESS TESTERS measuring hardness measure the residual
increment in the depth of the tip after unloading:
         - on a scale HRA - control of superhard alloys by the indenter "diamond cone",
         - on a scale HRB - control of materials of medium hardness by an indenter "steel ball",
         - on a scale HRC - control of hardened and tempered parts, indenter "diamond cone".
       2. BRINELL HARDNESS TESTERS (HB, HBW scales) according to the indentation
diameter control the hardness of non-hardened steel, cast iron, non-ferrous metals, soft bearing
alloys by means of a steel carbide ball with a diameter from 1.0 to 10.0 mm.
       3. VIKKERS HARDNESS TESTERS (HV scale) along the diagonal of the print of the
diamond pyramid control the hardness of small products, thin materials, coatings and films.
      4. SHORE HARDNESS TESTERS (HSD scale) determine the hardness of the rolling rolls
by the height of the rebound of the striker, and the Shore hardness meter (scales HA, HD, HC)
determines the hardness of rubber, polymers and porous materials by introducing an indenter into
the surface of the material.
       5. PORTABLE T HARDNESS TESTERS measure the hardness of ferrous, non-ferrous
metals, stainless and low alloy steels, using the direct method of the Lieb scale (HL) with the
conversion of hardness values ​​to the values ​​of the corresponding standard scales of Rockwell
(HR), Brinell (HB), Vickers (HV) and Shore ( HSD).
     You can calibrate in a NAAU accredited laboratory "MICROTECH" in accordance with the
requirements of the standard ISO 17025-17, while "MICROTECH" performs service and repair of
hardness testers with their subsequent calibration.
