Hardness measures the resistance to localized plastic deformation caused by force or abrasion. Materials with high hardness are generally stronger and more wear-resistant but can be more brittle.
The formula to convert Brinell Hardness (HB) to Rockwell Hardness (HRC) is:
\[ \text{HRC} = 0.95 \times \text{HB} + 11.5 \]
Consider a material with a Brinell Hardness (HB) of 200:
Using the formula:
\[ \text{HRC} = 0.95 \times 200 + 11.5 = 201.5 \]
This means the Rockwell Hardness (HRC) is 201.5.
