Al Summan Metals, a leading manufacturer and supplier based in Dubai, UAE, is recognized for producing high-quality Duplex Steel Hex Bars distinguished by their outstanding strength, corrosion resistance, and lasting durability. Through the use of advanced manufacturing methods and strict quality control practices, Al Summan Metals ensures that every Duplex Steel Hex Bar meets international standards, delivering reliable performance even in the most demanding industrial environments. These hex bars are prized for their distinctive combination of austenitic and ferritic stainless steels, offering superior toughness, stress corrosion resistance, and excellent weldability. Al Summan Metals provides precision-engineered duplex steel solutions ideally suited for chemical, petrochemical, marine, and offshore applications where durability is essential.
Duplex Steel Hex Bars are made up of roughly 22% chromium, 5–6% nickel, 3% molybdenum, and mostly iron, together with small quantities of nitrogen and additional alloying elements. This particular composition delivers exceptional mechanical strength, toughness, and impressive resistance to pitting, crevice corrosion, and stress corrosion cracking. Regarding mechanical properties, duplex steel hex bars offer a tensile strength between 700 and 900 MPa, yield strength from 450 to 550 MPa, and an elongation of 25 to 30%. The material additionally demonstrates good ductility, fatigue resistance, and weldability, which makes it an ideal option for demanding structural and industrial applications.

Yes, Duplex Steel Hex Bars can be completely recycled. They may be melted and reused without sacrificing their core properties, making them an eco-friendly, sustainable choice for a wide range of applications.
Duplex Steel Hex Bars offer natural corrosion resistance thanks to their makeup. Nevertheless, in extremely harsh conditions, extra coatings or treatments might be required to boost their durability and effectiveness.
Selecting the appropriate Duplex Steel Hex Bar requires weighing factors like mechanical strength, resistance to corrosion, temperature conditions, and how well it aligns with your application's particular industry standards and environmental factors.
Duplex Steel Hex Bars are widely employed across the chemical, petrochemical, marine, and offshore sectors thanks to their remarkable corrosion resistance, high strength, and durability. They are frequently used in pump shafts, valves, fasteners, heat exchangers, pressure vessels, and structural components exposed to severe conditions. Furthermore, these bars play a vital role in seawater systems, oil and gas platforms, and industrial machinery where both mechanical strength and corrosion resistance matter greatly. Owing to their outstanding mechanical properties, duplex steel hex bars deliver long-lasting performance, dependability, and safety in tough industrial settings.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
