Brinell to Rockwell C Conversion Formula:
| From: | To: |
The Brinell to Rockwell C conversion provides an approximate relationship between two different hardness measurement scales. This conversion is useful when comparing materials tested using different hardness testing methods or when specific equipment is not available.
The calculator uses the conversion formula:
Where:
Explanation: This formula provides an approximate conversion between Brinell and Rockwell C hardness scales, which is particularly useful for steel and other metallic materials.
Details: Accurate hardness conversion is crucial for material selection, quality control, and ensuring mechanical components meet specified hardness requirements across different testing methods.
Tips: Enter the Brinell hardness value (HB) in the input field. The value must be greater than 0. The calculator will automatically compute the approximate Rockwell C equivalent.
Q1: How accurate is this conversion?
A: This conversion provides an approximate value. For precise measurements, actual testing with the appropriate hardness scale is recommended.
Q2: What materials is this conversion suitable for?
A: This conversion works best for steel and similar metallic materials. Accuracy may vary for non-ferrous metals and other materials.
Q3: What are typical HB and HRC ranges?
A: Brinell hardness typically ranges from 100-700 HB, while Rockwell C typically ranges from 20-70 HRC for most industrial applications.
Q4: When should I use actual testing instead of conversion?
A: For critical applications, quality control, or when precise hardness values are required, always use actual hardness testing with the specified scale.
Q5: Are there limitations to this conversion?
A: Yes, this is an approximate conversion and may not be accurate for all materials, heat treatments, or extreme hardness values.
