Reference data and engineering information about bhn brinell hardness number for material properties applications.

bhnbrinellhardnessnumberCalculator

Overview

The Brinell hardness number (BHN) is determined by pressing a hardened steel ball into a material and measuring the indentation diameter.

Formula

BHN=2PπD(D−D2−d2)BHN = \frac{2P}{\pi D (D - \sqrt{D^2 - d^2})}

Notes

  • Results are approximate and should be verified for critical applications
  • Input values should be within reasonable engineering ranges
