ASTM E18-20 Rockwell Hardness Standard Test Methods astm rockwell hardness

Apr 21, 2020 · Rockwell Hardness Standard Test. The Rockwell hardness test, according to ASTM E18-20, is an indentation hardness test that involves the use of a verified machine to force a diamond spheroconical indenter or tungsten carbide (or steel) ball indenter into the surface of a material. Hardness is evaluated by measuring the difference in depth of the indentation as the force on the indenter is

Rockwell Hardness - an overview ScienceDirect Topics

Rockwell standard hardness scales and applications. A widely used variant of the Rockwell hardness test is the superficial Rockwell test, wherein the minor load is 3 N and the major loads are 15, 30, or 45 N. Further details on the Rockwell superficial hardness scales are available in the relevant ASTM standards (ASTM 1984).
