Hardness measurement consists of pressing the indenter into the inspected material beyond the limit of elasticity until plastic strain occurs. In practical terms, hardness can be defined as a measure of a material’s resistance to plastic strain.
Hardness measurements are very often used in the industry as simple and quick tests, thanks to the correlation of a material’s hardness and its strength. Hardness measurements are used for material quality control, particularly after heat treatment or heat and chemical treatment.
We use KB Pruftechnik GmbH type KB 30 S FA hardness tester.
Hardness tests are performed in conformity with the following standards:
PN-EN ISO 9015-1:2011 - Destructive tests on welds in metallic materials — Hardness testing — Part 1: Hardness test on arc welded joints
PN-EN ISO 6507-1:2018-05 - Metallic materials — Vickers hardness test — Part 1: Test method
PN-EN ISO 6506-1:2014-12 - Metallic materials — Brinell hardness test — Part 1: Test method
PN-EN ISO 6508-1:2016-10 - Metallic materials — Rockwell hardness test — Part 1: Test method
