Test Methods After Production

Mechanical testing:
With a 400 kN-tensile testing machine we determine the strength and elongation values with for our steel products at BESSEY’s in-house laboratories and if requested these values will be authenticated in writing. The requirement for hardness is monitored with suitable testing machines in HV and HB.

Chemical testing:
Samples are taken from each BESSEY steel production lot, which can be compared with their chemical analysis (up to 20 material identifying elements) by the help of an emission spectrometer. Thus, an accurate batch assignment is ensured.

Archiving of samples:
To ensure the traceability of material, samples of each steel production lot are archived up to 3 years. The obtained test results are stored 15 years.

All requirements of the magnetic properties of a material, such as it‘s coercivity field strength, permeability, etc. can be monitored with our Remagraph and if necessary, could also be documented.

Metallographic examination:
Experienced personnel conducts research studies of structure and degree of purity using a microscope with magnification of up to 1,000-fold.
