Ferromagnetic steels are very important industrially for their numerous applications in the electric and electromagnetic sectors.

They are defined as magnetically soft steels, characterised by high magnetic permeability and used in the production of solenoids, relays and petrol / diesel injectors for automobiles.

These applications require that the steel be easily magnetised and demagnetised. Groups of stainless steels have been designed with ferritic structures and a specific analytical balance that guarantees improved resistance to corrosion and good magnetic properties.

Where there is the need for particular resistance to corrosion for a specific purpose or environment, when very high magnetic permeability values and equally low coercive force values are required, Iron Silicon alloys are the only solution, but one that requires careful analysis of appropriate surface protection methods because of the tendency of these alloys to rust easily.
