Hardness is the property of a material that enables it to resist plastic deformation, usually by penetration.
However, the term hardness may also refer to resistance to bending, scratching, abrasion or cutting.
It is essential to evaluate the value of the hardness of welding and other materials to understand their usefulness in the process.
We have a non-indenting type tool which gives very accurate reading in any position. We also measure hardness of non-ferrous and rubber parts.
