Perhaps, the most controversial discussions in the hardness testing circles are the difference in the three most popular hardness testing methods. The Rockwell, Brinell, and Vickers hardness testing methods are generally used for different scenarios and situations. However, hardness testing professionals have sometimes found it hard to agree on the most suitable method based on their differences. The differences will help you indicate the most appropriate method for your peculiar hardness testing technique. This article aims to distinguish these methods and help you find the most suitable one for your testing situation. Without further ado, let’s dive in.
I. Why are Different Hardness Tests and Scales Required?
One benefit of testing material for hardness is its ability to confirm the strength and capacity of the material to withstand a level of force and ascertain other material properties, including elasticity, wear and tear resistance, and durability.
The thing is, engineers and hardness testing professionals have been presented with different hardness testing scales that they’ve come to accept. And while having several hardness testing methods might seem like a lot, the variety of testing methods ensures that the most suitable testing procedure is available when certain situations and environments do not allow the use of other methods.
