What Are The Different Grades Of Super Duplex Steel?

Some of the common grades of Super Duplex Steel with its unique properties and applications mention below:

• UNS S32750 (F53) : Apart from UNS S32750 it is also called as F53, is a type of Super Duplex Steel well-known for its exceptional corrosion resistance and high strength. This grade contains elevated levels of chromium, molybdenum, and nitrogen, contributing to its superior resistance against chloride-induced stress corrosion cracking and pitting corrosion. Moreover, UNS S32750 offers good weldability and formability, making it suitable for various applications in aggressive environments such as offshore oil and gas production, chemical processing, and marine engineering. Its high strength and corrosion resistance combination makes it an ideal choice for critical components in demanding conditions.
• UNS S32760 (F55): On the other hand, UNS S32760, also known as F55, is another grade of Super Duplex Steel that surpasses S32750 in terms of corrosion resistance and mechanical properties. It contains a higher content of chromium, molybdenum, and nitrogen and also includes tungsten, which further enhances its resistance to corrosion and erosion. UNS S32760 exhibits superior strength, toughness, and fatigue resistance, making it suitable for applications where high reliability and durability are crucial. It is commonly utilized in aggressive environments such as chemical processing plants, desalination facilities, and power generation systems, where resistance to chloride-induced corrosion and high temperatures is essential.
• Other Super Duplex Steel Grades: Apart from UNS S32750 and UNS S32760, other less commonly used grades of Super Duplex Steel are available. These grades are designed explicitly with unique compositions and properties tailored for specific applications. They may incorporate variations in alloying elements to achieve specific performance characteristics or to meet industry standards. While UNS S32750 and UNS S32760 are widely preferred due to their balanced strength and corrosion resistance combination, other grades may be chosen for specialized applications or to fulfil specific project requirements.

What are the Advantages of Using Super Duplex Pipes?

The super duplex steel pipe grades consist of 2507, which has a high chromium content of 28%, and 4501 duplex pipes. These duplex pipes are used in various applications such as seawater systems, umbilicals, desalination plants, flue-gas cleaning, pressure vessels, and tanks.

Duplex and super duplex belong to the stainless steel family and offer enhanced corrosion resistance and strength. Industries that require high levels of chlorine and temperature rely on these more robust stainless steel options. Duplex is the second generation stainless steel, which includes additional chromium, nickel, and molybdenum. On the other hand, the super duplex is the third generation with the same components but in higher quantities. As a result, there are several distinctions between the two, including the following.
