Benefits of hardness tests:

Ability to verify the heat treatment of a part in heat-treating operations and case depth analysis

Ability to determine if a material has the necessary properties for its intended use

Non-destructive test alternative for effectively qualifying and releasing material or components for target applications

Low cost and quick performance

There are different methods to test the hardness of the material including Rockwell hardness test, Brinell hardness test, Vickers hardness test, and Knoop hardness test. The choice of testing methods depends on the size, structure and hardness of products.
