Cómo funciona un durómetro Rockwell
Principio del ensayo de indentación Rockwell
The tester measures material hardness by evaluating indentation depth under a controlled load.
Major Load and Minor Load Process
Rockwell testing uses a minor preload followed by a major testing load.
Lectura e interpretación de los valores de dureza
Results are displayed directly in Rockwell hardness scales such as HRC or HRB.
