03Cr25Ni7Mo4WCuN dual phase steel F55

03Cr25Ni7Mo4WCuN Super Duplex Stainless Steel Overview:

03Cr25Ni7Mo4WCuN is a high alloy super duplex stainless steel, which is mainly used in various strong corrosion environments. 03Cr25Ni7Mo4WCuN dual-phase 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. 03Cr25Ni7Mo4WCuN dual-phase steel has better comprehensive properties than ordinary dual-phase steels, such as 2205, S31803, etc.

03Cr25Ni7Mo4WCuN dual-phase 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. 03Cr25Ni7Mo4WCuN is also resistant to strong alkali corrosion, but 03Cr25Ni7Mo4WCuN dual-phase 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.
