F55 dual phase steel 1.4508, X2CrNiMoCuWN25.7.4

F55 (S32760, 1.4508) Super Duplex Stainless Steel Overview:

F55 is a high alloy super duplex stainless steel, which is mainly used in various strong corrosive environments. F55 duplex steel has strong strength and corrosion resistance, and is mainly used in chemical processing, petrochemical and subsea equipment. It has strong resistance to chloride corrosion, higher thermal conductivity and lower coefficient of thermal expansion. The high chromium, molybdenum and nitrogen content makes it highly resistant to pitting, crevice corrosion and other corrosion. F55 dual-phase steel has better comprehensive properties than ordinary dual-phase steels, such as 2205, S31803, and so on.

F55 duplex steel is resistant to various inorganic and organic acids. At the same time, the added copper element makes it have excellent resistance to non-oxidizing acid corrosion. F55 also resists strong alkali corrosion, but F55 duplex steel is not suitable for long-term working temperature Use at temperatures above 300 ° C, because above this temperature, the toughness of the material will be significantly reduced.
