What is Rockwell hardness test? The Rockwell hardness test is a hardness measuring method using Rockwell scale to measure the depth of penetration of an indenter under a large load on the surface. Rockwell scale has different scales denoted by a single letter.
Brinell Hardness Test BHN The Brinell Hardness Test consists of indenting the test material with a 10mm diameter hardened steel or carbide ball subjected to a load of kg. Vickers Hardness Test HV The Vickers Hardness Test uses a diamond indenter in the form of a right pyramid with a square base and an angle of degress between opposite faces.
Other Hardness Scales The Rockwell, Brinell, and Vickers are the most common hardness scales, but there are many others: — Shore Scleroscope — Knoop — Leeb HLD : Leeb is a rebound hardness test that was developed in to provide a portable hardness test for metals.
