Rockwell Test - an overview | ScienceDirect Topics

The Rockwell test infers the hardness from the depth of penetration and thus enables a direct reading of hardness to be obtained from the instrument. Hard materials are measured on the Rockwell C scale using a diamond rounded tip cone indenter and a load of kN. Softer metals are measured on the Rockwell B scale using a steel ball of about mm diameter and a

Rockwell Hardness Tester -

Rockwell hardness tester, the world's first tester designed on the principle of the Rockwell scale, was co-invented by Hugh M. Rockwell (1890–1957) and Stanley P. Rockwell (1886–1940) in 1914. The patent for this instrument was granted in the year 1919. At first, this instrument used only the single side contact to inspect the hardness of metals. There was no need for sample

Rockwell Hardness Testing | Buehler

Rockwell hardness values are expressed as a combination of a hardness number and a scale symbol representing the indenter and the minor and major loads. The hardness number is expressed by the symbol HR and the scale designation. The most common indenter type is a diamond cone ground at 120 degrees for testing hardened steels and carbides.
