Al Summan Metals is a highly regarded manufacturer and supplier based in Dubai, UAE, focusing on premium-grade **Super Duplex Steel Flat Bars**. Known for its precision engineering and strict quality control, Al Summan Metals produces flat bars that deliver exceptional strength, corrosion resistance, and durability. These Super Duplex Steel Flat Bars are built to perform dependably in demanding industrial environments, particularly where they encounter severe conditions such as chloride exposure, acidic surroundings, or elevated temperatures. Serving industries like chemical processing, oil and gas, marine, and power generation, Al Summan Metals ensures products that comply with international standards, delivering lasting operational efficiency.
Super Duplex Steel Flat Bars generally 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 delivers remarkable tensile and yield strength together with outstanding corrosion resistance. The material typically offers a tensile strength of 800–1000 MPa, yield strength of 550–750 MPa, and elongation of 25–30%. It demonstrates outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-heavy conditions, while retaining toughness and dimensional stability at elevated temperatures.

Yes, Super Duplex Steel Flat Bars are highly recyclable. Owing to their makeup and durability, they can be repurposed across many industries without sacrificing their properties or performance.
Super Duplex Steel Flat Bars are typically unsuitable for cryogenic applications because they become brittle at extremely low temperatures. Materials such as austenitic stainless steel are frequently favored for these purposes.
Super Duplex Steel Flat Bars are indeed appropriate for underground use, thanks to their outstanding resistance to corrosion, particularly in tough, corrosive settings like exposure to soil or groundwater.
Super Duplex Steel Flat Bars are widely applied in industries that call for exceptional corrosion resistance and mechanical strength. They see frequent use in chemical and petrochemical processing equipment, heat exchangers, pressure vessels, offshore platforms, and marine hardware. Within the oil and gas industry, these bars play a vital role in pipelines, valves, and pumps subjected to seawater or harsh chemicals. Their remarkable strength-to-weight ratio and durability further make them well-suited for structural parts in power generation facilities, desalination systems, and other industrial uses that require dependable, long-lasting performance.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
