What Are Super Duplex 2507, 32750 & 32760 Pipes?
Super Duplex 2507 (UNS S32750), 32750, and 32760 pipes represent the pinnacle of duplex stainless steel technology, featuring a balanced dual-phase microstructure of approximately 50% austenite and 50% ferrite. These super duplex grades contain elevated levels of chromium (24-26%), molybdenum (3-5%), nickel (6-8%), and nitrogen (0.24-0.32%), resulting in a Pitting Resistance Equivalent Number (PREN) exceeding 40-45, which provides exceptional resistance to chloride pitting, crevice corrosion, and stress corrosion cracking.

Applications and Uses of Super Duplex Stainless Steel 2507 / 32750 / 32760 Pipes
Understanding the diverse applications of Super Duplex stainless steel pipes helps buyers recognize opportunities where these materials can provide superior performance. This knowledge expands potential use cases and project possibilities.Super Duplex 2507 pipes excel where regular duplex grades reach their limits. Key application sectors include:
- Oil & Gas
- Chemical & Petrochemical
- Desalination & Water Treatment

- Pulp & Paper
- Pharmaceutical & Food Processing
- Mining & Metallurgy
Manufacturing Process of Super Duplex Stainless Steel Pipes
Familiarity with the manufacturing process of Super Duplex stainless steel pipes gives buyers confidence in product quality and consistency. Understanding production methods ensures reliable material properties.
- Raw Material Selection
Choosing the right inputs is the foundation of super duplex pipe production. High-purity iron ore is combined with key alloying elements—chromium for corrosion resistance, nickel for ductility, molybdenum for pitting resistance, and nitrogen for strength. Exact proportions (around 25% Cr, 5% Ni, 3.5% Mo) are critical to achieve the desired duplex microstructure. - Melting and Refining
The blended raw materials enter an electric arc or vacuum induction furnace, where temperatures soar above 1,600°C (2,912°F). Impurity removal and precise alloy adjustments take place here, ensuring the molten steel reaches the stringent chemistry required for super duplex grades. - Casting
Once refined, the liquid steel is solidified into workable forms. Continuous casting yields long slabs ready for rolling, while ingot casting produces large blocks that are later reheated and shaped. Each method offers control over grain structure and material consistency. - Hot Working
The cast slabs or billets are then transformed into pipe through high-temperature processes. Billet extrusion pushes heated metal through a die, creating seamless tubes, while piercing techniques introduce a hollow core for larger diameters. This stage refines grain size, bolstering mechanical strength. - Cold Working
After forging shape, the tubes may be cold drawn or stretch formed to tighten dimensional tolerances and improve surface finish. This work hardens the steel, boosting yield strength and ensuring precise, uniform dimensions. - Heat Treatment
Solution annealing at roughly 1,050°C (1,922°F) followed by rapid quenching dissolves any secondary phases and locks in a balanced ferrite-austenite structure. In some cases, a controlled aging step enhances specific properties, optimizing both toughness and corrosion performance. - Finishing Operations
Final touches include pickling and passivation to strip away oxides and promote a passive surface film. Depending on customer needs, pipes can be polished or coated for enhanced appearance, additional corrosion protection, or improved weldability.

Frequently Asked Questions About Super Duplex Stainless Steel Pipes
Super Duplex 2507 contains higher chromium (24–26% vs. 22%), molybdenum (3–5% vs. 3%), nickel (6–8% vs. 5–6.5%), and nitrogen, giving it greater pitting resistance, corrosion strength, and nearly double yield strength compared to 2205.
Yes. Super Duplex grades like 2507 exhibit minimum yield strengths of 550–580 MPa and tensile strengths up to 800 MPa, roughly 20–30% higher than standard Duplex 2205.
Super Duplex 2507 performs excellently in chloride-rich and acidic settings, with a PREN above 40. It is recommended for service temperatures up to about 300 °C (572 °F), as higher sustained temperatures may reduce toughness.
Super Duplex 32760 has dual-phase microstructure and exhibits magnetic permeability around 33 at 20 °C, making it weakly magnetic but suitable for applications requiring controlled magnetic response.
