Super Duplex Steel
Super Duplex Stainless Steel offers superior resistance to stress corrosion cracking and excellent mechanical properties compared to other steels. This alloy combines austenitic and ferritic structures with added molybdenum for enhanced performance. It is known for its strong resistance to pitting and impressive tensile strength.
Ideal for both onshore and offshore oil and gas applications, Super Duplex Steel provides high corrosion resistance in challenging environments. At Kalpataru Piping Solutions, all Super Duplex materials are rigorously tested to meet international standards. For more details on Super Duplex piping, explore our industry-specific pages.
Characteristics of Super Duplex Stainless Steel
Super Duplex Stainless Steel, a high-performance material developed in Sweden over 70 years ago, is known for its exceptional resistance to corrosion and stress. It was initially designed to combat corrosion from aggressive chemicals and cooling waters with chlorides.
This steel features a balanced microstructure of ferrite and austenite, which enhances its properties. Super Duplex is distinguished by its high pitting resistance and alloying elements, such as chromium, nickel, and molybdenum. The addition of nitrogen further improves its strength and resistance without sacrificing toughness.
Super Duplex Steel is commonly used in industries like chemicals, petrochemicals, and marine applications, where it often replaces traditional stainless steels and nickel-based alloys. Its two-phase structure offers superior resistance to pitting and stress corrosion cracking, making it a popular choice for demanding environments. Recent advances have also enabled the production of high-strength steel wires as thin as 1 mm.

FAQ
What are super duplex materials?
Super duplex steels are high-performance alloys with about 25% chromium content. They feature a microstructure consisting of both austenitic and ferritic phases, combining the benefits of both to offer high strength, excellent corrosion resistance, and improved durability.
What is the grade of super duplex steel?
Super duplex steels, such as F53 (UNS S32750) and F55 (UNS S32760), fall within the PREN (Pitting Resistance Equivalent Number) range of 38-45. These grades are known for their enhanced corrosion resistance and high mechanical strength due to their high chromium, molybdenum, and nitrogen content.
What is Super duplex stainless steel?
Super duplex stainless steel is a high-performance material characterized by its dual-phase microstructure of austenitic and ferritic grains. It offers exceptional strength and superior corrosion resistance, making it suitable for demanding applications in harsh environments.
