Conversion Formula:
| From: | To: |
The HV to BHN conversion allows you to convert Vickers hardness values to Brinell hardness numbers. This conversion is particularly useful for steel materials where the approximate relationship BHN ≈ HV × 0.95 applies.
The calculator uses the conversion formula:
Where:
Explanation: This conversion provides an approximate relationship between Vickers and Brinell hardness scales specifically for steel materials.
Details: Converting between different hardness scales is essential when comparing material specifications, quality control data, or when working with historical data that uses different measurement systems.
Tips: Enter the Vickers hardness value (HV) in the input field. The value must be greater than 0. The calculator will automatically compute the approximate Brinell hardness number.
Q1: How accurate is this conversion?
A: This conversion provides an approximate value specifically for steels. Accuracy may vary for different materials and hardness ranges.
Q2: Can this conversion be used for all materials?
A: No, this conversion factor is specifically calibrated for steel materials. Other materials may require different conversion factors.
Q3: What is the difference between Vickers and Brinell hardness tests?
A: Vickers uses a diamond pyramid indenter while Brinell uses a hardened steel or carbide ball. Vickers is better for harder materials and smaller areas.
Q4: When should I use direct measurement instead of conversion?
A: For critical applications or material certification, always use direct hardness measurement in the required scale rather than conversions.
Q5: Are there limitations to hardness conversions?
A: Yes, conversions are approximations and may not account for material-specific characteristics, surface conditions, or testing variations.
