How a Steel Hardness Tester Works
Arbeitsprinzip
A steel hardness tester measures hardness by applying force to a steel surface and analyzing the response. The method used depends on the type of tester.
Indentation Method
This involves pressing an indenter into the steel surface and measuring the size or depth of the indentation.
Rebound Method
This method measures how an impact body rebounds from the steel surface, which correlates with hardness.
Both methods are widely used in different types of steel hardness tester devices.
Types of Steel Hardness Tester
Rockwell Steel Hardness Tester
