Regular Rockwell hardness test: In this test, a load of 60, 100, or 150 kg is applied to the surface of the material for a few seconds, depending on the hardness of the material. . The Rockwell hardness test uses an indenter, typically a diamond cone or steel ball, that is pressed into the surface of the material being tested. The depth of .Rockwell hardness test measures the permanent depth of indentation on the material by applying a fixed load using an indenter. The smaller the indentation value, the harder is the material. The Rockwell hardness test follows the principle of the differential-depth method.Rockwell Regular hardness =130 0 002 − h, HRN HRTW Rockwell Superficial hardness =100 0 001 − h, 4.2 The following is an example of the designation of Rockwell hardness.

Regular, superficial and combination units available to operate in all Rockwell scales in regular and superficial Rockwell ranges. Available in several capacities. The Indentron Series hardness testers feature an innovative cantilevered indenter configuration that eliminates frictional inconsistencies typical of competitive testing systems.An indentation hardness test using a verified machine to force a diamond spheroconical indenter or tungsten carbide (or steel) ball indenter, under specified conditions, into the surface of the material under test, and to measure the difference in depth of the indentation as the force on the indenter is increased from a specified preliminary .The test method for Rockwell testing (ASTM E-18-08a) only allows the use of tungsten carbide ball indenters. AMETEK makes a variety of Newage indenters and indenter accessories. We recommend that you contact us , for assistance in specifying and ordering an indenter for your Rockwell , Brinell or Microhardness application.
Hardness tests can be defined as forcing an hardness testing indenter of a specified size, shape, and material into the surface of a test piece to obtain a hardness value. .
