How much pressure do we use in bore gauge while checking? What are the two Hardness commonly use for inspection?

Question

Accepted Answer

The pressure used in bore gauge varies depending on the specific application. Two common hardness scales used for inspection are Rockwell and Brinell.

Pressure used in bore gauge varies based on the specific application and material being measured
Common hardness scales used for inspection include Rockwell and Brinell
Rockwell hardness testing involves measuring the depth of penetration of an indenter under a large load (e.g. HRC)
Brinell hardness testing involves measuring the diameter of an indentation left by a hard steel or carbide ball under a known load (e.g. HB)
