What is Super Duplex Steel S32760 Round Bars? This alloy, also known by its UNS designation S32760 (sometimes marketed under the trade name Zeron 100), features a balanced microstructure of roughly 50% austenite and 50% ferrite. It belongs to the ASTM A182 / ASME SA182 Grade F55 family, offering a PREN (Pitting Resistance Equivalent Number) of at least 40. Its chemical composition typically includes ~24–26% chromium, 6–8% nickel, 3–4% molybdenum, 0.2–0.3% nitrogen, along with additions of copper and tungsten.

At SMM Industries LLP, we deal in Super Duplex Steel S32760 Round Bars Manufacturers, offering high-precision, solution-annealed bars in a variety of finishes (black, bright polished, matt) and diameters. Our production process ensures compliance with both ASTM A182 / A479 and equivalent international standards such as EN 1.4501 and DIN 1.4410.

Super Duplex Steel S32760 Round Bars combine the best of duplex metallurgy: high tensile strength (up to ~750 MPa) and 0.2% proof stress around 550 MPa. The balanced microstructure imparts exceptional resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking, especially in chloride-laden environments such as seawater. Its PREN of ≥ 40 ensures outstanding localized corrosion resistance. The alloy’s high nitrogen content improves strength without compromising ductility, while additions like tungsten and copper further augment corrosion resistance. Weldability and fabricability of S32760 are also very good when processed correctly, and components maintain excellent impact toughness even at sub-zero temperatures.

Our strong network enables us to serve as reliable Super Duplex Steel S32760 Round Bars Suppliers, stocking a broad range of sizes—from small diameters (6 mm) to large (up to 350 mm)—and offering custom length cutting to client specifications.

Super Duplex Steel S32760 Round Bars uses and applications appear across major industries. Their presence makes operations smooth in sectors that need long performance cycles and resistance to corrosion. These uses include:

• Oil & Gas Industry: In offshore rigs, Super Duplex Steel S32760 Round Bars are used in critical structural components, valve stems, and high-pressure connectors, thanks to their superb strength and corrosion resistance.

• Marine Engineering: These bars serve in shipbuilding, seawater piping systems, and desalination plants, where exposure to chloride-rich environments demands materials highly resistant to pitting and stress corrosion.

• Chemical Processing: The bars perform excellently in chemical plants, particularly in heat exchangers, reactors, and process equipment exposed to aggressive acids, chloride solutions, and high temperatures.

• Power Generation: Super Duplex S32760 bars are employed in steam exhausts, condensers, and boiler components, where they resist corrosion and fatigue under cyclic loading.

• Pulp & Paper / Mining: In pulp bleaching plants or mining operations, these round bars are used because of their resistance to sulfuric acid, high strength, and long service life.

• Water Treatment and Desalination: Structural components, manifolds, and shafts made from S32760 round bars are ideal for reverse osmosis, brine pipelines, and other desalination applications.
