Alloy 32760 is a super duplex stainless steel supplied in the hot worked and solution annealed condition. As a super duplex stainless steel, it combines the desirable aspects of both austenitic and ferritic grades. The higher chromium, molybdenum and nitrogen contents result in a Pitting Resistance Equivalent number (PREN) of >40, providing pitting and crevice corrosion resistance superior to austenitic and duplex stainless steels in almost all corrosive media, and a Critical Pitting Temperature exceeding 50°C nb. versions of the PREN formula also include W as a positive influence on overall pitting resistance. The super duplex microstructure has the high strength of the ferritic grades whilst retaining the corrosion resistance of the austenitic grades. It is not uncommon to see the metal used as a practical solution to chloride-induced stress cracking, which is the Achilles’ heel of stainless steel.
Super duplex steel S32760 provides higher strength than both austenitic and 22% Cr duplex stainless steels, and is listed in NACE MR 0175 for sour service and ASME for pressure vessel applications. Containing 25% chromium, 7% nickel, 3.6% molybdenum as well as copper, tungsten, and nitrogen, UNS S32760 is a highly alloyed super duplex stainless steel use in aggressive environments. It also has outstanding resistance against sulphide-stress corrosion cracking in sour-gas environments. Well known for its high impact strength, UNS S32760 displays no ductile-brittle transition but only a slight reduction in impact energy as temperature decreases. Even when welded, UNS S32760 displays only slightly lower impact strength.
Super Duplex Steel S32760 bar have become high in demand for tough applications. The bars are having high tensile strength, ruggedly constructed, pitting/oxidation resistance, flexibility, durability, dimensional accuracy, fine surface finishes, and stress corrosion cracking resistance. This grade bar is also having a greater ability to be fully resistance to abrasion, erosion, withstanding heavy loads and easily hold high temperature. That is why the bars have become very good for various applications in many industries all across the globe.
Our Super Duplex Steel UNS S32760 Round Bars have high strength, superior corrosion resistance, resistance to chloride-induced stress cracking, and outstanding resistance against sulphide-stress corrosion cracking in sour-gas environments. Super Duplex Steel S32760 Round Bars exhibit superior resistance to erosion corrosion and corrosion fatigue, outstanding resistance to general corrosion, high mechanical strength, etc.

Super duplex steel S32760, also known as 2507, is a highly corrosion-resistant alloy that combines the properties of both austenitic and ferritic stainless steel. This alloy has a high content of chromium, molybdenum, and nitrogen, which provides excellent resistance to pitting, crevice, and stress corrosion cracking. It is also known for its high strength and toughness, making it suitable for demanding applications.
S32760 is commonly used in the oil and gas industry, especially in offshore platforms, subsea applications, and marine environments. Its exceptional resistance to corrosion in seawater, combined with its high strength, makes it ideal for components exposed to harsh oceanic conditions. Examples include piping systems, pressure vessels, heat exchangers, and valve components.
In environments where aggressive chemicals, such as chlorides, acids, and alkalis, are present, S32760 provides superior performance. It is widely used for heat exchangers, reactors, and storage tanks, where corrosion resistance and mechanical strength are critical.
Due to its resistance to seawater corrosion, S32760 is often used in desalination plants, where it can be found in the piping systems, pumps, and valves that transport seawater or brine.
S32760 is also employed in the pulp and paper industry where equipment is exposed to aggressive chemical environments. It is used in digesters, bleaching towers, and recovery systems.
In power plants, especially in systems dealing with high-temperature and high-pressure steam, S32760 round bars are used for critical components like boilers and heat exchangers, owing to their strength and resistance to thermal fatigue and corrosion.
The alloy is also used in the food and beverage industry for equipment like mixers, tanks, and other components where hygiene and resistance to corrosive environments are crucial.
Due to its resistance to corrosion and biocompatibility, S32760 is used for manufacturing equipment such as mixers, storage tanks, and piping systems that handle various pharmaceutical and biotechnological substances.
In conclusion, S32760 round bars are essential in many industries that require materials with high strength and excellent resistance to corrosion in harsh environments. The versatility of this alloy ensures its continued use in critical applications such as offshore drilling, chemical processing, and power generation.
