Various methods are typically used to measure the hardness of special steel. The most common method is the Rockwell hardness test, which involves pressing a diamond or hardened steel ball into the surface of the steel to measure the depth of penetration. The Rockwell hardness number is determined based on the difference in depth before and after the application of a minor load and a major load. Another widely used method is the Brinell hardness test, which involves indenting a hardened steel or carbide ball into the steel surface and measuring the diameter of the indentation. The hardness is calculated based on the applied load and the diameter of the impression. Additionally, for specific applications, other methods like the Vickers hardness test and the Knoop hardness test are often employed. These tests require indenting the steel surface with a diamond pyramid to measure the diagonal lengths or the indentation depth, respectively. Ultimately, the hardness of special steel is determined by assessing its resistance to indentation or penetration. This information is valuable in understanding the mechanical properties of the steel and determining its suitability for different applications.
