Clean Steel

Non-metallic microinclusions in steels are a problem that the metallurgical industry must overcome in producing a new generation of clean steels.

In traditional steels microinclusions are produced during hot working processes, and can generate microfractures that may propagate themselves under mechanical stress, possibly causing total structural failure.


Elettra's contribution

At Elettra, X-ray photoemission microspectroscopy techniques have been used to identify the chemical characteristics of these minute impurities and the phases of production primarily responsible for contamination. As a result, new working processes have been developed to reduce impurities to a minimum.
