- Super Duplex Steel UNS S32760 Tubes
Midland Alloys Inc. is a trusted manufacturer and supplier of Super Duplex Steel UNS S32760 tubes, offering high-performance solutions for demanding industrial applications. These tubes feature a dual-phase austenitic-ferritic structure, providing excellent strength and superior corrosion resistance, especially in chloride-rich and aggressive environments. Composed of 24–26% chromium, 3–4% molybdenum, and 6–8% nickel, the alloy resists pitting and stress corrosion cracking. Available forms include U-tubes, seamless (SMLS), cold-drawn, and coil tubes, compliant with standards such as ASTM A789, ASTM A928, ASME SA789, and DIN/EN. Elbows, tees, reducers, and stub ends are also available as fittings. With ISO-certified facilities, ready stock, and worldwide shipping, we provide a timely and consistent supply of Super Duplex UNS S32760 tubes in a range of sizes, wall thicknesses and pressure classes.
Benefits of Super Duplex Steel UNS S32760
- High Strength: Super Duplex UNS S32760 tubes provide superior tensile and yield strength, which ensures they are perfect for high-load and pressure applications.
- Excellent Corrosion Resistance: These tubes are resistant to pitting, crevice corrosion, and chloride stress cracks due to their high concentrations of chromium, molybdenum, and nitrogen.
- Weldability: The alloy supports efficient welding without the risk of cracking or phase imbalance when proper welding procedures are followed.
- Durability: Its strong structure and chemical stability provide extended service life even in extreme marine, chemical, or heat exchanger environments.
- Versatility: Offered in various forms such as UNS S32760 seamless tubing, coil tubes and heater tubes, these are applicable in oil & gas, desalination and paper industries.
- Low Maintenance: Compared to conventional austenitic, or ferritic stainless steels, maintenance costs are reduced due to its strength and resistance to corrosion.

Difference between Super Duplex Steel UNS S32760 vs Duplex Steel UNS S32205 Tubes
Super Duplex Steel UNS S32760 and Duplex Steel UNS S32205 differ in alloy content, strength, and corrosion resistance. UNS S32760 has a higher amount of chromium, molybdenum, and nickel, which makes it more resistant to pitting, crevice corrosion, and stress corrosion cracking than UNS S32205. It also provides greater tensile and yield strength, making it suitable for more demanding applications. While UNS S32205 performs well in moderate conditions, S32760 excels in aggressive chloride environments and high-pressure systems. For industries needing superior mechanical and chemical performance, especially in subsea, offshore, or chemical processing, UNS S32760 is the preferred choice.

Applications of Super Duplex Steel UNS S32760
Super Duplex Steel UNS S32760 finds application in environments where strength and corrosion resistance are very important. In the oil and gas sector, it is applied to heat exchangers, pressure vessels and subsea pipelines. The petrochemical and chemical industries use it for chemical process piping, storage tanks, and scrubbers because it can withstand acidic and chlorinated conditions. The pulp and paper industries, seawater desalination plants and marine engineering also use it. Applications such as ASTM A928 UNS S32760 heater tubes, ASTM A789 UNS S32760 bright annealed tubes, and Duplex UNS S32760 seamless tubes are widely used across these industries for their dependability and long-term performance.

FAQs
Super-duplex UNS S32760 steel tubes are also referred to as Zeron 100 tubes. They provide high strength, and superior corrosion resistance, particularly in severe environments.
The key difference is that super duplex steel contains higher chromium, molybdenum and nitrogen content compared to duplex steel, which makes it stronger and more corrosion-resistant.
