Tools for hardness testing vs Hardness Conversion Master

With this app you can quickly convert your hardness values according to the commonly used standards of the world of hardness testing. Vickers Curvature Correction Calculator: Save the time and trouble of using look up tables: determine your curvature corrected Vickers value with this quick calculator. Spacing / Thickness Calculator (Vickers / Knoop): ISO and ASTM specify that Vickers hardness test indentations must be a distance of at least three times their diagonal apart and the minimum thickness of the specimen must be over 1.5 times the diagonal length. In order to conform to the standards, use the calculator to determine these dimensions for your test. Rockwell Thickness Calculator: When Rockwell testing on thin materials be sure that you are complying with ISO and ASTM standards of minimum thickness with this calculator before you test. Brinell Value Calculator: When using a handheld microscope to measure Brinell indentations, Brinell numbers are normally calculated using ISO 6506-4 tables. This Brinell number calculator quickly provides the Brinell number without the need to consult the tables. Conversion to ISO 18265 (part A1 and B2): The conversion tool for metallic materials uses the tables of ISO 18265. With this e.g. Vickers values can be revalued to tensile strength.

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
