Hardness testing | PPT

11. Hardness Testing: Indentation hardness • Brinell Non standard Hardness Test In this test, the loads are decreased and also the ball sizes are reduced. Ball indenters 1.25, 2.5 and 5.0 mm diameters with suitable reduced loads are used. The procedure of testing is similar to that of standard Brinell hardness test. The load should be selected such that the indentation …

Brinell Hardness Testing

The value of Rockwell hardness HR is given by (E–e), where E is a constant (130 for a steel ball indenter and 100 for a diamond cone indenter), and e is the permanent increase in penetration depth arising from the main load (divided by 0.002 mm). Readings above 100 HR for a ball indenter are rejected and a different scale is used to obtain ...
