Hardness testing

In hardness testing, also called hardness measurement, we use a force (load) where a ball or a tip (diamond pyramid) makes an impression in the material. A smaller impression means a harder material.

Hardness testing is done for several reasons:

  • Identification and distinction of phases
  • Determination of hardness profiles in welded joints
  • Determination of hardness profiles in surface hardened materials
  • Measurement of hardness in basic material
  • Measurement of surface hardness in fasteners
  • Measurement of hardness in surface layers
  • Evaluation of diffusion (mainly carburization and decarburization)
  • Evaluations of segregation
  • Evaluations of deformation
  • Control of curing depth
  • Estimation of tensile strength
