Hardness testing and hardness profile measurements of metallic components and workpieces as well as hardness testing of thin hard material layers by means of the instrumented penetration method or hardness testing on weld seams.
In many cases it is important to know the hardness of a component. The hardness is a total factor that depends on a material's plastic and elastic behaviour and is determined by the structure as well as by chemical composition.
In comparison with all other technological test procedures, hardness testing can be performed more quickly, less destructively and more easily. Hardness measurements are typically integral to the assessment of material quality, the heat treatment condition and the influence of different production methods.
Hardness and tensile strength correlate to a certain extent. It is therefore possible to convert not only between individual hardness units but also from hardness to tensile strength in compliance with the applicable standards. Here, it should always be taken into account that these conversions constitute only estimates.
