The positive material identification is made to analyse and identify the metals and their alloys composition for the quality and process control.
Even small changes in terms of the concentration of a material may affect its mechanical and electrical properties in a significant way.
In ARTEN, our raw materials are subjected to a 100% double check, both at the entrance and during the production process. The analysis is made with a portable micro-X-ray fluorescence spectrometer.
The XRF portable technique requires the absence of contaminants on the surface, like protection oils or oxidation layers, and it’s efficient also on rough and irregular surfaces.
This analysis determines the chemical composition of the material, which is the starting point for a correct classification of the material itself.
With this verification, we avoid mistakes by the worker or an exchange of material in stock and during the production process. There is an important chemical difference between AISI 304L and AISI 316L, invisible to the naked eye, but fundamental on a practical level and for the chemical resistance of the final product.
The controls we implement thanks to the spectrometers in our factory allow us to supply our customers a certification of the material, which is confirmed thanks to these analysis and tests which take place starting from the arrival of the raw material to the delivery of the final product.
