Al Summan Metals, a well-regarded manufacturer and supplier based in Dubai, UAE, focuses on premium Super Duplex Steel Rectangular Bars built to deliver superior performance in demanding industrial environments. These bars are made to provide high strength, outstanding corrosion resistance, and impressive durability, which makes them ideal for demanding engineering applications. Through a dedication to precision and compliance with international standards, Al Summan Metals ensures excellent dimensional accuracy and surface finish. The Super Duplex Steel Rectangular Bars are built to withstand pitting, crevice corrosion, and stress corrosion cracking, making them a dependable option for marine, chemical, petrochemical, and offshore applications that require enduring performance.
These bars are made up mainly of chromium (25%), nickel (7%), and molybdenum (3.5%), together with nitrogen, tungsten, and copper, all of which combine to form a well-balanced austenite-ferrite microstructure. This distinctive makeup delivers strong resistance to corrosion from chlorides as well as oxidation. Their mechanical qualities are just as noteworthy, featuring a tensile strength of 800–850 MPa, a yield strength of 550 MPa, and elongation of roughly 25%. They also exhibit outstanding hardness, toughness, and fatigue resistance, allowing them to keep excellent stability and performance even under severe pressure and temperature conditions.

When choosing Super Duplex Steel Rectangular Bars, take into account elements such as corrosion resistance, mechanical strength, operating temperature, application environment, and adherence to industry standards to achieve optimal performance.
Yes, Super Duplex Steel Rectangular Bars can be joined through suitable methods like TIG or MIG welding. Nevertheless, adequate heat management is required to preserve their corrosion resistance and mechanical properties.
Super Duplex Steel Rectangular Bars are not well suited for cryogenic applications, since their toughness and ductility can be reduced at extremely low temperatures, which may cause brittleness in such conditions.
Al Summan Metals’ Super Duplex Steel Rectangular Bars are extensively employed across industries that demand exceptional mechanical strength and corrosion resistance. They are frequently used in offshore oil and gas platforms, desalination facilities, marine equipment, and chemical processing systems. Moreover, these bars serve in heat exchangers, pressure vessels, and structural parts subjected to high-stress and corrosive settings. Because they can withstand severe conditions and heavy loads, they represent an excellent option for power generation, pulp and paper processing, and seawater handling systems, ensuring longevity and dependable performance in every use.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
