Hardness Testing

During the manufacturing process of any metal products , there is the process of heat treatment and then of quenching. This is the uniform cooling of the heated product to obtain the desired strength. This process is dependent on numerous variables and has to be verified that it is carried out properly. If this is done in-correctly , there may be hard / soft spots which would during usage deteriorate rapidly.

To avoid catastrophic failures due to weak spots , Hardness values of critical components are often ascertained. Tuboscope Indonesia carries out Brinell Hardness Testing at numerous locations over Indonesia and this is done with sophisticated electronic equipment giving immediate reliable readings.

The portable equipment consists of a plunger with a calibrated spring mechanism. In this plunger a metal pellet is injected with precise force and this is reflected by the material under test.

The return velocity of the pellet is measured with the calibrated spring mechanism. This is then translated by a portable computer into a value called the Brinell Hardness Number or BHn.
