F55 Duplex Stainless Steel Bar
F55 (S32760, 1.4501) is a high alloy super duplex stainless steel, mainly used in a variety of strong corrosion environment. F55 duplex steel strength and corrosion resistance is stronger, mainly for chemical processing, petrochemical and seafloor equipment. It has strong resistance to chloride corrosion, high thermal conductivity and lower thermal expansion coefficient. Higher chromium, molybdenum and nitrogen content make it highly resistant to pitting, crevice corrosion and other corrosion. F55 (S32760, 1.45150) duplex steel excellent overall performance superior to the general dual-phase steel, such as 2205, S31803 and so on.
F55 (S32760, 1.45150) Duplex steel is resistant to a wide range of inorganic acids and organic acids. Its addition of copper gives it excellent resistance to non-oxidizing acid corrosion. However, the F55 is also resistant to alkali corrosion. However, the F55 (S32760, Duplex steels are not suitable for long-term service temperatures above 300 ° C because material toughness decreases significantly above this temperature.
