Al Summan Metals is a well-regarded manufacturer and supplier based in Dubai, UAE, focused on premium **Super Duplex Steel Bars and Rods**. Celebrated for their precision engineering and steadfast dedication to quality, Al Summan Metals guarantees that their products comply with international standards, delivering outstanding strength, corrosion resistance, and durability. These Super Duplex Steel Bars and Rods are engineered specifically for demanding industrial uses where protection against pitting, crevice corrosion, and stress corrosion cracking is critical. Serving industries such as chemical processing, oil and gas, marine, and power generation, Al Summan Metals supplies reliable, durable products capable of enduring even the most severe environmental conditions.
Usually, **Super Duplex Steel Bars and Rods** contain roughly 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, with iron making up the balance. This distinctive composition produces an impressive pairing of high mechanical strength and exceptional corrosion resistance. The bars and rods offer a tensile strength between 800 and 1000 MPa, yield strength from 550 to 750 MPa, and elongation of 25 to 30%. They stand up especially well to chloride-induced corrosion, demonstrating great toughness and superb performance at both normal and higher temperatures.

Super Duplex Steel rods typically resist galvanic corrosion thanks to their elevated chromium and molybdenum levels. Nevertheless, they may remain vulnerable when paired with highly dissimilar metals in particular environments.
Yes, Super Duplex Steel bars are weldable when suitable methods and filler metals are employed. Precise management of heat input and post-weld heat treatment is critical to prevent deterioration of their mechanical properties.
Super Duplex Steel rods come in a wide range of sizes, from small diameters up to large rods, generally reaching 300mm or beyond. Available finishes include hot-rolled, cold-drawn, polished, or ground, based on the specific needs of the application.
You’ll see **Super Duplex Steel Bars and Rods** commonly used across industries that require high strength together with corrosion resistance. They’re well suited to offshore platforms, marine hardware, chemical and petrochemical processing equipment, heat exchangers, and pressure vessels. Within the oil and gas sector, they serve in pipelines, valves, pumps, and risers exposed to seawater or aggressive chemicals. Their remarkable strength-to-weight ratio and durability likewise make them a great choice for structural components in power generation, desalination systems, and a range of other industrial uses where reliability and lasting performance matter greatly.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
