The 3 most popular hardness measurement procedures and when and how to apply them
“Hardness,” the quality that we define using a hardness measuring procedure, determines a material’s resistance to the external mechanical intrusion of measuring tools that are harder than the material itself.
The varying procedures for hardness measurement that have developed over the past two centuries are grouped into 4 general categories, based on the implemented intrusion techniques and measuring instruments. Each procedure has its advantages and disadvantages, and have been proven to suit the hardness measurement of particular categories of metals.
In this whitepaper, you’ll find:
- An overview of hardness measurement procedures
- A summary of the four groups of hardness measurement methods
- A short history, description and explanation, and pro/con analysis of the three most popular hardness measurement methods
- A table of metals and the hardness measurement procedure that is used for determining their hardness value
