Also known as Duplex, these steels are characterized by excellent resistance to corrosion under stress and pitting and by high mechanical characteristics.
Gieffeacciai has three austenic-ferritic steel in its catalogue: F51, F53 and F55 with an increasing PREN (Pitting Resistance Equivalent Number) and consequently with a better pitting resistance.
