Ball indenters:The same holds true for ball indenters. ASTM E18, the specification that covers Rockwell hardness testing, still permits the use of highspeed steel balls. One test on a very hard piece of steel (gt;58 HRC) will put a flat on the ball and produce high readings for the same reason that a broken diamond indenter does.
The Rockwell hardness test. Rockwell is a fast hardness test method developed for production control, with a direct readout, mainly used for metallic materials. The Rockwell hardness (HR) is calculated by measuring the depth of an indent after an indenter has been forced into

Jul 28, 2017#0183;#32;HR15N This method is known as Rockwell 15N. A relatively light, 15 kgf load is applied to case hardened parts treated to achieve a minimum effective case depth inches or a total case of inches. Other Rockwell variants (HR30N and HR45N) apply slightly higher loads on parts with incrementally higher minimum effective or total cases.

Dec 16, 2020#0183;#32;Rockwell Hardness Test Procedure. The Rockwell hardness test consists of indenting the test material with a diamond cone or hardened steel ball indenter. Different indenter ball diameters from 1/16 to 1/2 in. are used depending on the test scale. Each time a test is performed two loads are applied to the sample being tested.
