HRB to BHN Conversion Formula:
| From: | To: |
The HRB to BHN conversion provides an approximate relationship between Rockwell B hardness and Brinell hardness numbers. This conversion is useful for material selection, quality control, and comparing hardness measurements across different testing scales.
The calculator uses the conversion formula:
Where:
Explanation: This is an approximate conversion that provides a quick estimation between the two hardness scales. For precise conversions, refer to standardized conversion tables.
Details: Hardness conversion is essential in materials engineering for comparing test results from different hardness testing methods, ensuring material specifications are met, and facilitating communication between different testing standards.
Tips: Enter the Rockwell B hardness value (HRB) in the input field. The value must be positive. The calculator will provide the approximate Brinell hardness number (BHN).
Q1: How accurate is this conversion?
A: This is an approximate conversion. For precise applications, consult official conversion tables from standards organizations like ASTM or ISO.
Q2: What are typical HRB values?
A: HRB values typically range from 0 to 100, with common values for steels falling between 50-90 HRB.
Q3: When is this conversion most useful?
A: This conversion is most useful for quick estimations and preliminary material selection where exact precision is not critical.
Q4: Are there limitations to this conversion?
A: Yes, the relationship is not perfectly linear and varies with material type, heat treatment, and other factors. Always verify with standardized tables for critical applications.
Q5: Can this conversion be used for all materials?
A: This conversion works best for steels and similar metallic materials. It may not be accurate for non-ferrous metals, plastics, or other materials.
