Ideal for quality control tests of JIS steel materials! A hardness test that can infer tensile strength and other properties from measurement values!
The "hardness test" involves pressing a diamond or similar indenter into the surface of the test specimen and calculating the hardness value based on the diagonal length (area) or depth of the indentation created in the specimen. It is a general-purpose test that can be performed relatively easily, and from the obtained measurements, one can infer the tensile strength, crack resistance, wear resistance, and machinability of materials and welded joints.

Applications/Examples of results
【Application Examples】 ■ Quality control tests for JIS steel materials with specified hardness ■ Alternative tests when tensile testing cannot be performed due to size or shape constraints in carbon steel ■ Determination of the appropriateness of heat treatment conditions for steel materials ■ Evaluation of welding conditions through hardness distribution measurement of base metal, heat-affected zone, and weld metal in welded components ■ Surface hardening layer depth measurement tests for carburizing or nitriding layers ■ Investigation of material abnormalities by measuring hardness around damaged areas in damage surveys of mechanical structures *For more details, please refer to the catalog or feel free to contact us.
