Al Summan Metals distinguishes itself as a premier manufacturer and supplier based in Dubai, UAE, with expertise in high-quality **Super Duplex Steel Round Bars**. Celebrated for their precise engineering and steadfast quality, Al Summan Metals makes certain that their round bars comply with international standards, providing outstanding strength, corrosion resistance, and durability. These Super Duplex Steel Round Bars are engineered to perform in demanding environments, whether they encounter chloride exposure, acidic conditions, or elevated temperatures. Serving industries such as chemical processing, oil and gas, marine, and power generation, Al Summan Metals ensures products that deliver lasting operational efficiency and superior performance.
When it comes to composition, **Super Duplex Steel Round Bars** generally contain roughly 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, with iron accounting for the remainder. This mixture yields remarkable mechanical properties, delivering a tensile strength of 800–1000 MPa, yield strength of 550–750 MPa, and an elongation of 25–30%. The alloy shows especially strong resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments, all while retaining outstanding toughness and stability at elevated temperatures.

Yes, Super Duplex Steel Round Bars can handle moderately high temperatures but are not suited for extended use beyond 300°C, since this can diminish their corrosion resistance and mechanical properties.
Yes, Super Duplex Steel Round Bars are highly recyclable. Their materials, such as chromium, nickel, and molybdenum, can be repurposed, encouraging sustainability and cutting down on waste in industrial applications.
No, Super Duplex Steel Round Bars generally don't need extra corrosion protection coatings, since their high levels of chromium, molybdenum, and nitrogen deliver outstanding natural corrosion resistance even in demanding environments.
These **Super Duplex Steel Round Bars** are widely used in industries demanding exceptional corrosion resistance and mechanical strength. They’re ideal for offshore platforms, marine hardware, chemical and petrochemical processing equipment, heat exchangers, and pressure vessels. Within the oil and gas industry, they appear in risers, pipelines, valves, and pumps exposed to seawater or aggressive chemicals. Their remarkable strength-to-weight ratio and durability likewise make them well-suited for structural components in power generation, desalination plants, and other industrial uses that call for long-term reliability and performance.
We deliver products accompanied by both mill test certificates and third-party test certificates, guaranteeing top-tier quality and compliance standards.
