HRC to HRB Conversion Formula:
| From: | To: |
The HRB to HRC conversion provides an approximate relationship between Rockwell B and Rockwell C hardness scales. This empirical conversion is useful for comparing materials tested on different Rockwell scales.
The calculator uses the conversion formula:
Where:
Explanation: This is an empirical approximation for converting between Rockwell B and Rockwell C hardness scales.
Details: Converting between Rockwell scales is important when comparing materials tested with different indenters and loads, or when specifications require values in a different scale than what was measured.
Tips: Enter HRB value between 0-130. The calculator will provide the approximate HRC equivalent. Note that this is an empirical conversion and may not be exact for all materials.
Q1: How accurate is this conversion?
A: This is an empirical approximation. Accuracy varies by material type and actual conversion may differ based on specific alloy composition and heat treatment.
Q2: What are typical HRB and HRC ranges?
A: HRB typically ranges from 0-100 for softer materials, while HRC ranges from 20-70 for harder materials. The conversion is most reliable in overlapping ranges.
Q3: When should I use this conversion?
A: Use for general reference when comparing hardness values across different Rockwell scales, but for critical applications, direct measurement on the required scale is recommended.
Q4: Are there limitations to this conversion?
A: Yes, conversion accuracy decreases at extreme values and varies by material type. Different materials may require specific conversion tables.
Q5: Can this conversion be used for all metals?
A: While generally applicable to steel and similar alloys, specific non-ferrous metals may require different conversion factors or specialized conversion tables.
