Rockwell Hardness Testing and the ASTM E 18-03 Standard
Rockwell Hardness testing is a
system for determining hardness of metallic material. The E 18-03 standard
established by ASTM is a detailed description of the Rockwell Hardness testing
method.
A 120 degree angle diamond or 1/16” (1.588mm) diameter hard
steel ball indenter is pressed into the test piece surface with a preliminary
force P0 (10kgf) at a
depth D0. Then, a
main force P1 is
added until the total test force, P = P0 + P1, is 60kgf for HRA, 100kgf for HRB and
150kgf for HRC, and the indenter increases to a depth D2. Then, the
preliminary force P0 is unloaded, and the indenter decreases to a
depth D1. This results in a depth difference, e = D1 –
D0, measured in units of 0.002mm. The hardness reading for HRA and
HRC is 100-e, and for HRB is 130-e
