How a Metal Hardness Tester Works
Indentation Testing Principle
The tester applies force through an indenter to create a measurable indentation on the material surface.
Load Application and Hardness Measurement
Different test methods use specific loads and indenters based on material properties.
Hardness Scale Conversion and Analysis
Results are converted into scales such as HRC, HBW, HV, and others.
