F55 (S32760, 1.4501) is a high-alloy super-duplex stainless steel mainly used in various corrosion-resistant environments.

F55 dual phase steel has strong strength and corrosion resistance, mainly used in chemical processing, petrochemical and submarine equipment.

It has strong resistance to chloride corrosion, high thermal conductivity and low coefficient of thermal expansion.

The higher content of chromium, molybdenum and nitrogen gives it high resistance to spot corrosion, crack corrosion and other corrosion abilities.
