Isis Metals stands out as a top manufacturer and supplier located in Manila, Philippines, with a focus on high-quality Super Duplex Steel Bars and Rods. These products are crafted for exceptional strength, durability, and resistance to corrosion, making them perfect for tough industrial and marine settings. Isis Metals serves a diverse array of industries, including oil and gas, petrochemical, power generation, construction, and marine sectors. With a commitment to precision engineering, quality assurance, and customer satisfaction, Isis Metals guarantees that its Super Duplex Steel Bars and Rods provide outstanding performance, longevity, and reliability even in the most challenging conditions.
Super Duplex Steel Bars and Rods are made up of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen, all balanced with iron and trace elements. This unique dual-phase microstructure of ferrite and austenite gives them remarkable mechanical strength and corrosion resistance. The material boasts a high tensile strength ranging from 800 to 1,000 MPa, along with excellent yield strength and impressive toughness, even in freezing temperatures. Super Duplex Steel is particularly resistant to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides, making these bars and rods perfect for harsh and corrosive environments.

Super Duplex Steel rods are generally resistant to galvanic corrosion due to their high chromium and molybdenum content. However, they can still be susceptible when coupled with highly dissimilar metals in certain environments.
Yes, Super Duplex Steel bars can be welded using appropriate techniques and filler materials. Careful control of heat input and post-weld heat treatment is essential to avoid degradation of their mechanical properties.
Super Duplex Steel rods are available in various sizes, ranging from small diameters to large rods, typically up to 300mm or more. Finishes can include hot-rolled, cold-drawn, polished, or ground, depending on the application requirements.
Isis Metals’ Super Duplex Steel Bars and Rods are widely utilized in industries where high strength and corrosion resistance are crucial. They are frequently found in the oil and gas sector for applications like pipelines, valves, heat exchangers, and offshore structures. In the chemical and petrochemical fields, they serve in process equipment, pressure vessels, and storage tanks. The marine and shipbuilding industries rely on them for shafts, fasteners, and structural components that come into contact with seawater. Additionally, they are used in desalination plants, power generation facilities, and pulp and paper production, showcasing their versatility across various demanding applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
