The Rockwell hardness test method consists of indenting the test material with a diamond cone or hardened steel ball
indenter. The key benefit of the Rockwell hardness test is that it can show direct hardness values. This test is widely
used because of its: Reliability, Speed, Resolution, Robustness, and Small indentation area.
Based on product type, the Rockwell Hardness Testers Market is classified into Digital Rockwell Hardness Tester,
Portable Rockwell Hardness Testers. Based on application, the global market is classified into R&D departments,
Inspection departments, foundries, educational institutions, laboratories, and heat treatment shops. Based on scale,
the Rockwell Hardness Tester Market is classified into HRA, HRB, HRC, and others, where the last letter is the particular
Rockwell scale.
On the basis of Rockwell hardness test, a differential-depth method, the residual depth of the indent made by the
indenter is measured. The sequence of the Rockwell test according to ISO 6508 can be described as below:
The indenter is pressed with the test pre-force (also referred to as preload) to a penetration depth of h0 in the
specimen to be tested. h0 defines the reference level for subsequent measurement of the residual indentation depth
(h).The additional test force is applied for a dwell period defined in accordance with the standard (several seconds),
whereby the indenter pierces into the specimen to a maximum indentation depth of h1. The test pre-force plus the
additional test force gives the total test force (also referred to as main load).After the dwell period, the additional test
force is removed; the indenter moves up by the elastic proportion of the penetration depth in the total test force and
remains at the level of the residual indentation depth (h - expressed in units of 0.002 or 0.001 mm). This is also referred
to as the depth differential (difference in indentation depth before and after application of the total test force). Now
the Rockwell hardness (HR) can be calculated, using the residual indentation depth (h) and a formula defined in the
standard, taking account of the applied Rockwell scale. Geographically, the global market is segmented into North
America, China, Europe, Southeast Asia, Japan, and India.
