If you work with metals and other materials regularly, chances are that sooner or later, you will need to know the Vickers hardness of a material. The Vickers hardness test is one of the most commonly used methods for determining the hardness of various materials. The Vickers hardness test measures the ability of a surface to resist penetration when pressed by a fixed force. In other words, it measures how much pressure is needed to embed an indenter into a material and measure its impact on a load cell.
There are several ways to express this measurement in different units. Luckily, you do not have to remember all of them because we’ll show you a simple HRB to Vickers hardness conversion chart. Keep reading and learn more about each unit of measure.
I. What is HRB Hardness?
HRB is a scale that represents the Rockwell Hardness level of a material. It measures the resistance of a surface coming into contact with a diamond indenter. Usually, materials are tested using an indenter that has a specified diameter, but in some cases, other equivalent indents may be used, such as 0.25 – 0.33 inches (measured at depth).
II. What is Vickers Hardness?
Vickers Hardness is a microhardness test conducted on small metallic materials with thin sections or case depth work. Vickers hardness is a measure of the resistance of a surface to indentation using a diamond indenter.
Vickers hardness test is an automated hardness testing method used to determine the resistance of materials to indentation. The procedure involves applying a specified load on different areas of a sample surface to determine its ultimate resistance when any point of contact between the indenter and sample surface is taken beyond the point that causes deformation.
III. How do you Convert Rockwell Hardness to Vickers?
The Vickers hardness conversion chart helps you find the Vickers hardness for any given Rockwell hardness. This conversion method uses the Rockwell ratio to express the relationship between Vickers Hardness and Rockwell Hardness.
The conversion chart follows the ASTM standards to give an accurate conversion between Rockwell Hardness and Vickers Hardness.
IV. Rockwell B to Vickers Hardness Conversion Chart
Rockwell B(100kg, 1/16″ Ball)
The Vickers hardness test can measure the relative hardness of different metals and other materials. Whether you need to convert from HRB to Vickers or vice versa, you will find this chart very useful.
This chart should be used only as a reference, not as a substitute for testing your material’s hardness. You should use an actual Vickers hardness test to accurately test your material’s hardness.
