Description
S32760 (F55,1.4501) is a high-alloy super duplex stainless steel, mainly used in a variety of highly corrosive environments. S32760 duplex steel strength and corrosion resistance, mainly used in chemical processing, petrochemical and offshore equipment. It has excellent resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient. The high chromium, molybdenum and nitrogen content has a high resistance to pitting, crevice corrosion and other corrosion. S32760 duplex steel excellent overall performance is better than ordinary dual-phase steel, such as 2205, S31803, etc.
S32760 duplex steel ability of various inorganic acids and organic acids, while its copper added that it has excellent resistance to non-oxidizing acid corrosion, is also resistant to alkali corrosion S32760, S32760 duplex steel but not suitable for long-term temperature 300 ℃ above case used because above this temperature, the material toughness will be significantly reduced.
