Convert HB to HRC

What is Hardness?

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.

Formula

The formula to convert Brinell Hardness (HB) to Rockwell Hardness (HRC) is:

\[ \text{HRC} = 0.95 \times \text{HB} + 11.5 \]

Example Calculation

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.
