We often get inquiries about what kind of tests do you perform on the products. For castings, one of the most important tests is hardness test. It is a very critical measure for the material and we test hardness for all the products we manufacture. Of cousre, a trustworthy hardness tester is an essential piece in our lab. Starting today, I will be beginning a new series of introducing our testing equipments. Today’s topic is hardness tester.
How it works?
Brinell hardness test is an indentation hardness test. An applied force (a typical test will use 3,000 kilograms) pushes the ball against the surface of the material for a set amount of time (between 10 – 30 seconds, known as the dwell time).
The diameter of the resulting indentation in the surface is then measured at least twice on perpendicular angles.
Sample size: we follow GB/T standard to make a test bar with every batch.
