Features
Read full description

A professional hardness conversion tool designed for mechanical engineering, metal heat treatment, and quality management, providing quick, stable, and traceable engineering reference data. **Key Features** 1. **Industrial-Grade Precision** The conversion logic is based on ASTM E140 / ASTM A370 standards, utilizing high-density reference points and linear interpolation to deliver stable and reproducible conversion results. 2. **Flexible Input and Real-Time Synchronization** Allows direct input in any hardness field (e.g., HRC / HV / HBW), with real-time conversion across other units, enhancing on-site operational efficiency. 3. **Physical Range Protection Mechanism** Built-in effective range checks for each scale, displaying "No Reference Value" when out of range, reducing the risk of misinterpretation. 4. **Customizable Interface** Enables toggling unit displays and drag-and-drop sorting to create a workspace tailored to individual or production line processes. 5. **Image Conversion (Beta)** Supports photo/album import, area selection recognition, result comparison, and manual correction, suitable for quick conversion of reports and on-site records. 6. **Batch Conversion** Allows multiple data entries for rapid conversion, retaining the last used unit preference to minimize repetitive actions. **Supported Units** - Rockwell: HRC, HRA, HRB, HRD, HRF - Superficial Rockwell: HR15N, HR30N, HR45N, HR15T, HR30T, HR45T - Brinell: HB, HBW - Vickers: HV - Tensile Strength: MPa
