Super duplex stainless steel grades are characterised by the nature of their dual microstructure. The alloy of these flanges contains an equal 50% ratio of each ferrite and austenite. Which would mean that the super duplex flanges would inherit the properties of both austenitic as well as ferritic classes of stainless steel, making it a valued alloy across industries such as Fire-fighting systems, Subsea control lines, Heat exchangers, Offshore platforms as well as Injection & ballast water systems. For instance, properties such as superior ductility and formability, is the reason why this alloy can be manufactured into different shaped components like flanges. In terms of its mechanical properties, the Super Duplex UNS S32750 Flanges have high tensile strength and yield strength of 570 MPa.

A combination of its high mechanical strength along with excellent corrosion resistance properties makes these flanges a predominant sight in the oil and gas industry. super duplex stainless steel flanges have a higher content of elements molybdenum and chromium which promotes the material’s corrosion resistance to a much higher level than that of conventional duplex grades. The flanges also exhibit outstanding resistance to corrosion in marine environments, thus proving to be an important alloy in the field of marine engineering. Speaking of localized attack, the PREN value or Pitting Resistance Equivalent number of super duplex 2507 flanges is more than 40, thus, guaranteeing high resistance to pitting corrosion. In addition to its high resistance to crevice corrosion and stress corrosion cracking super duplex steel flanges can be used in both ambient and sub-zero temperatures (down to minus 50°C) as the notch ductility is good.
