S32900, W.Nr.1.4460 duplex steel 0Cr25Ni5Mo2

S32900 (0Cr25Ni5Mo2, 1.4460) Super Duplex Stainless Steel Overview:

S32900 is a high alloy super duplex stainless steel, which is mainly used in various strong corrosive environments. S32900 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. The excellent comprehensive properties of S32900 dual-phase steel are superior to ordinary dual-phase steels, such as 2205 and S31803.

S32900 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. S32900 also resists strong alkali corrosion, but S32900 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.
