The Brinell Hardness to Rockwell Calculator is a valuable tool used in materials science and engineering to convert between two common measures of material hardness: Brinell Hardness (HB) and Rockwell Hardness (HR). While both measurements assess the resistance of a material to permanent deformation caused by indentation, they utilize different testing methods and scales. The calculator simplifies the conversion process, providing users with quick and accurate results.
Formula of Brinell Hardness to Rockwell Calculator
The formula used to calculate Rockwell hardness (HR) from Brinell hardness (HB) is:
HR = 100 - (0.36 * HB)
General Terms Table
| Term | Description |
|---|---|
| Brinell HB | The Brinell hardness of a material |
| Rockwell HR | The Rockwell hardness of a material |
| Conversion | The process of converting one hardness scale to another |
| Indentation | A mark or impression left by a hardness testing tool |
Adding a general terms table provides users with additional context and terminology related to hardness testing, enhancing their understanding of the subject.
Example of Brinell Hardness to Rockwell Calculator
Suppose we have a material with a Brinell hardness of 200 HB. To find its Rockwell hardness using the calculator:
HR = 100 - (0.36 * 200) = 100 - 72 = 28 HR
Therefore, the Rockwell hardness of the material is 28 HR.
Most Common FAQs
A: Different applications and industries may require hardness measurements in specific scales. Converting between Brinell and Rockwell hardness allows for compatibility with various standards and specifications.
A: While this calculator specifically converts Brinell to Rockwell hardness, similar tools exist for converting between other hardness scales, such as Vickers to Rockwell or Rockwell to Shore.
A: No, material strength depends on various factors, including composition, microstructure, heat treatment, and environmental conditions, in addition to hardness.
