kovuusluokkia
Kovuusluokkia is a Finnish term used to describe categories that express the hardness of a material, specifically the material’s resistance to permanent deformation, scratching, or indentation on its surface. It is a way to classify how hard a material appears under certain test conditions.
Hardness is not a single property but a set of related measures. The most familiar hardness scales
Hardness is influenced by a material’s composition, microstructure, heat treatment, and surface finish. For metals, increasing
Tests to determine hardness follow standardized procedures, applying a specific load with a defined indenter and
Kovuusluokkia is used in materials selection, manufacturing quality control, and engineering analyses to assess suitability for
