Frequently Asked Questions

What is the best hardness tester?
The Rockwell method is the most universal because it uses both a penetrating diamond cone and a penetrating steel ball to measure material hardness. The diamond cone is used on hardened steel and hard metals, but not recommended below 785 N/mm² hardness.
What is a digital hardness tester?
Automatic reading uses a digital camera that captures the image and performs calculations to determine the diameter of the impression in mm and the HBW (Hardness Brinell) number.
What does a Rockwell hardness tester check?
The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load).
Why is hardness testing necessary?
Hardness testing enables evaluation of material properties such as strength, ductility and wear resistance, helping determine whether a material or material treatment is suitable for specific applications.
How do I find Rockwell hardness number?
The Rockwell hardness number is calculated from the depth of permanent deformation of the indenter into the sample - the difference in indenter position before and after application of the major load.
