Metallography

The technicians’ COMPETENCE and COMMON SENSE are fundamental in Metallography. Our STRENGTHS are: our constant attention to staff TRAINING and our wide EXPERIENCE supported by the tests successfully carried out together with INTER-LABORATORY CIRCUITS.

In Metallography the technicians’ COMPETENCE and COMMON SENSE are fundamental. Our STRENGTHS are: our constant attention to staff TRAINING and our wide EXPERIENCE supported by the positive results of the tests carried out together with INTER-LABORATORY CIRCUITS.
We SPECIALIZE in micrographic and macrographic tests such as:
- determination of non-metallic INCLUSIONS
- assessment of the average dimensions of the GRAIN
- assessment of the MICROSTRUCTURE and presence and quantification of PHASES and/or PRECIPITATES
- THICKNESS measuring of hardened superficial layers (CEMENTATION, NITRIFICATION and SUPERFICIAL TEMPERING) or of coatings
- determination of DECARBURIZATION depth
- evaluation (also geometrically) of WELDED or BRAZED JOINTS
