1. What is HRC to HV Conversion?

The HRC (Rockwell C) to HV (Vickers) hardness conversion provides an approximate equivalent value between these two hardness scales. This is useful when comparing materials tested with different methods or when specifications require values in a different scale.

2. How Does the Calculator Work?

The calculator uses the approximate conversion formula:

Where:

• \( HRC \) — Rockwell C hardness value
• \( HV \) — Vickers hardness value

Note: This is an approximate conversion. For precise conversions, consult official hardness conversion tables.

3. Importance of Hardness Conversion

Details: Hardness conversion is essential when comparing materials tested with different methods or when specifications require values in a particular scale. Different industries may prefer different hardness scales.

4. Using the Calculator

Tips: Enter HRC value (typically between 20-70 HRC for most steels). The calculator will provide the approximate equivalent HV value.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this conversion?
A: This provides a rough approximation. For precise conversions, consult official ASTM or ISO hardness conversion tables.

Q2: What materials is this conversion valid for?
A: Primarily for steels. Different conversion factors may apply to other materials like aluminum or copper alloys.

Q3: Why are there different hardness scales?
A: Different scales were developed for different material types and hardness ranges. Rockwell is faster for production testing while Vickers can test a wider range of materials.

Q4: What's the range of validity for this conversion?
A: Best for HRC values between 20-70. Outside this range, the approximation becomes less accurate.

Q5: When should I use actual conversion tables instead?
A: For critical applications, quality control, or when precise equivalency is required, always use official conversion tables.
