Al Summan Metals, a highly regarded manufacturer and supplier based in Dubai, UAE, specializes in producing high-quality Duplex Steel Bars and Rods engineered for outstanding strength and corrosion resistance. Equipped with advanced production facilities and strict quality control procedures, Al Summan Metals ensures that its products meet international standards for both performance and dependability. Serving a range of sectors such as chemical processing, oil and gas, marine, and power generation, the company is committed to supplying reliable and accurate materials. Recognized for their technical expertise and steady quality, Al Summan Metals’ Duplex Steel Bars and Rods offer excellent mechanical performance, withstand stress corrosion cracking, and retain lasting durability even under demanding industrial and severe environmental conditions.
These Duplex Steel Bars and Rods consist of roughly 22% chromium, 5–6% nickel, 3% molybdenum, and 0.14% nitrogen, while the balance is iron along with minor elements such as manganese, silicon, and carbon. This distinctive two-phase composition of austenite and ferrite provides them with outstanding mechanical characteristics, including high tensile strength (620–850 MPa), superb yield strength, and solid toughness. The alloy is recognized for its strong resistance to pitting, crevice corrosion, and stress corrosion cracking, which makes it ideally suited to harsh chemical and chloride-heavy settings. This combination of strength and corrosion resistance guarantees reliable performance in tough applications.

Yes, Duplex Steel Bars provide outstanding corrosion resistance, especially when it comes to stress corrosion cracking, pitting, and crevice corrosion. Thanks to their dual-phase microstructure, they perform better in demanding environments.
Duplex steel bars hold up well in high-heat conditions thanks to their outstanding strength and their ability to resist oxidation and scaling. The dual-phase microstructure boosts thermal stability and toughness when subjected to heat stress.
Duplex steel rods can indeed be customized in both size and length to suit particular application needs. They can be adapted to a range of dimensions and tolerances to serve different industries.
Duplex Steel Bars and Rods are widely applied in industries demanding superior strength and resistance to corrosion under harsh environments. They work exceptionally well for producing pumps, valves, flanges, fittings, shafts, and fasteners across oil and gas, chemical, and petrochemical facilities. Within marine and offshore environments, they provide defense against seawater and chloride-induced corrosion. Additionally, they are used in power generation, desalination facilities, and pulp and paper processing machinery, where toughness and mechanical strength are crucial. Al Summan Metals’ Duplex Steel Bars and Rods genuinely distinguish themselves in the market through their dependability and quality.
We provide products supplied with both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
