The W-B92 Webster
Hardness Tester is calibrated using
HRB standard Rockwell hardness blocks, with a measurement range equivalent to 48-100HRB. This hardness range covers almost all common soft steel materials. Comparative tests show that the measured values of the W-B92 hardness tester have an approximate linear relationship with HRB Rockwell hardness values, as shown in the figure below. The W-B92 hardness tester can be used as a convenient HRB Rockwell hardness tester.Applications
* Inspect the effectiveness of material heat treatment to determine if the mechanical properties meet standards.
* Determine if the material has been improperly alloy processed.
* Differentiate material hardness grades. Identify material heat treatment states such as annealed, 1/8 hard, 1/4 hard, 1/2 hard, and full hard.
* Online inspection and control of strip steel material hardness.

Hardness Blocks
The standard hardness blocks used with the instrument are made of aluminum alloy or low carbon steel, with a hardness value of approximately 55HRB Rockwell hardness. Each hardness block comes with an inspection report.
Conversion
Users can determine the conversion relationship between Webster hardness values and Vickers hardness values (HV) or Rockwell hardness values (HRB) through testing.
