Al Summan Metals, a highly regarded manufacturer and supplier based in Dubai, UAE, focuses on premium Super Duplex Steel Hex Bars engineered for outstanding strength, corrosion resistance, and lasting durability. These hex bars are precisely manufactured to meet international quality standards, ensuring superior performance even in the most demanding conditions. Thanks to their balanced microstructure of austenite and ferrite, they deliver excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Sectors such as oil and gas, marine, chemical processing, and power generation choose Al Summan Metals’ Super Duplex Steel Hex Bars for their dependability and long service life.
These Super Duplex Steel Hex Bars contain roughly 25% chromium, 7% nickel, and 3.6% molybdenum, together with small quantities of copper, tungsten, and nitrogen, which combine to deliver superb resistance to corrosion and oxidation. They exhibit remarkable mechanical characteristics, including a tensile strength of 800–850 MPa, a yield strength of 550 MPa, and an elongation of about 25%. Owing to their duplex microstructure, they offer exceptional hardness, toughness, and fatigue resistance, holding onto their strength and stability even in high-pressure, high-temperature, and corrosive industrial environments.

Yes, Super Duplex Steel Hex Bars exhibit magnetism because their combined microstructure of austenite and ferrite grants them magnetic characteristics, although they are less magnetic than ferritic steels.
Super Duplex Steel Hex Bars are indeed well-suited for hygienic and sanitary uses thanks to their resistance to corrosion, longevity, and simple cleaning, which makes them perfect for sectors such as food processing and pharmaceuticals.
Super Duplex Steel Hex Bars are less prone to galvanic corrosion than other materials owing to their strong corrosion resistance. Nevertheless, they can still undergo galvanic corrosion when placed in contact with metals that are less resistant.
Al Summan Metals’ Super Duplex Steel Hex Bars are extensively used in industries where strong mechanical properties and resistance to corrosion are essential. They are ideally suited for use in offshore oil and gas platforms, desalination facilities, chemical processing equipment, and marine engineering. These bars are also employed in pumps, shafts, valves, fasteners, and pressure vessels exposed to severe, chloride-heavy environments. Their outstanding machinability and accurate dimensions make them well-suited for both structural and mechanical uses, delivering durability, performance, and reliability in essential industrial operations.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
Al Summan Metals is a leading manufacturer, supplier, and exporter of high-quality bars, rods, and forgings, catering to various industries in Dubai, UAE
