Brief Introduction to Hardness Tester

Hardness is one of the important criteria of the mechanical functions of the materials, and the hardness test is the important means to judge the quality of the metallic materials or parts.

As the metallic hardness has mutual correspondent relations with other mechanical functions, the majority of the metallic materials can calculate the other mechanical functions such as the strength, the fatigue, the evolutionary change and the degree of being worn out can be approximately inferred from the hardness shown by the test.
