Brinell to Rockwell C Conversion Formula:
| From: | To: |
The Brinell to Rockwell C conversion formula provides an approximate conversion between two different hardness measurement scales. This conversion is useful when comparing material specifications or when only one type of hardness measurement is available.
The calculator uses the conversion formula:
Where:
Explanation: This empirical formula provides an approximate conversion between the two hardness scales. The relationship is linear with a conversion factor of 0.34 and an offset of -13.
Details: Hardness conversion is essential in materials engineering, quality control, and manufacturing processes where different hardness testing methods may be used interchangeably or when comparing material specifications from different sources.
Tips: Enter the Brinell Hardness Number (BHN) in the input field. The value must be greater than 0. The calculator will provide the approximate Rockwell C Hardness (HRC) value.
Q1: How accurate is this conversion?
A: This conversion provides an approximate value. For critical applications, direct measurement using the appropriate hardness test is recommended.
Q2: What are typical BHN and HRC ranges?
A: BHN typically ranges from 100-700 for most steels, while HRC ranges from 20-70 for hardened steels.
Q3: When should I use this conversion?
A: Use this conversion for general reference and material selection. For precise engineering calculations, use actual measured values.
Q4: Are there limitations to this conversion?
A: Yes, the conversion may vary depending on material type, heat treatment, and other factors. It works best for carbon and alloy steels.
Q5: Can this conversion be used for all materials?
A: No, this conversion is primarily valid for steels. Different conversion factors may be needed for non-ferrous materials.
