Hardness is a property that applies to a number of materials, such as metals and nonmetals, and is defined as the material's resistance to deformation, penetration, scratching or other physical strength. EUROLAB experts measure the hardness according to the requirements of the material and its applications with equipment that is precisely calibrated to the appropriate hardness scales.
The direct, timely and relatively non-destructive nature of the hardness test makes it one of the most popular features for engineers interested in material selection, batch verification testing, evaluation of material processing or comparing hardness values between multiple material samples. In addition, hardness values can typically be closely related to other material properties, such as tensile strength.
OLUROLAB's expertise in static deformation stiffness methods includes both macro hardness (loads applied over 1 kg) and micro hardness (loads applied less than 1 kg) in accordance with most industry standards. The known geometry and mass forced on the surface of the material, the amount of force applied along with the depth of the recess are recorded and used to calculate the appropriate hardness value for a given point on the sample. Multiple recesses are typically made to provide an average hardness value for the entire sample.
As part of our On-Site Metallographic Analysis, we use versions of the portable hardness test to perform on-site hardness measurements in large installations or equipment that are impossible or impractical to send to a laboratory. We perform on-site hardness measurements by the following methods:
EUROLAB can prepare the surface for each of the above methods and suggest the most suitable method for your specific project needs. Thanks to a team of multidisciplinary engineers and global access to advanced testing equipment, our hardness measurement services offer portability, flexibility and high performance for on-site metal verification.
