Starc Metals, a leading manufacturer and supplier located in Canberra, Australia, is all about high-quality Super Duplex Steel Hollow Bars. They focus on delivering precision-engineered and durable solutions that meet the demands of tough industrial applications. These hollow bars are celebrated for their remarkable strength, outstanding corrosion resistance, and long-lasting performance. Crafted with advanced techniques and strict quality control measures, Starc Metals ensures that every product meets high standards of quality and dimensional accuracy. They cater to various industries, including oil and gas, chemical processing, marine, and petrochemical sectors, offering a range of Super Duplex Steel Hollow Bars in different sizes, grades, and finishes. Their components are designed to perform reliably, even in extreme environmental and operational conditions.
Super Duplex Steel Hollow Bars are made from a well-balanced alloy that includes chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen, resulting in a duplex microstructure of ferrite and austenite. This unique composition provides excellent corrosion resistance, especially against pitting, crevice corrosion, and stress corrosion cracking, all while maintaining impressive mechanical strength. Typical mechanical properties include a tensile strength of 750–900 MPa, yield strength of 550–700 MPa, and elongation of 25–30%. These hollow bars are known for their exceptional toughness, weldability, and durability, making them perfect for critical and high-performance applications.

Yes, Super Duplex Steel Hollow Bars can withstand high temperatures due to their excellent strength and corrosion resistance. They are suitable for applications in environments up to around 300°C (572°F), depending on the specific alloy.
Super Duplex Steel Hollow Bars and Rods are manufactured through hot or cold working processes, including extrusion and forging, followed by heat treatment, cold drawing, and precision machining for enhanced strength and corrosion resistance.
Super Duplex Steel Hollow Bars have excellent natural corrosion resistance due to their high chromium and molybdenum content, making additional protective coatings generally unnecessary. However, in highly aggressive environments, coatings may offer extra protection.
In industries that require strong, corrosion-resistant, and durable tubular components, Super Duplex Steel Hollow Bars are a go-to choice. In the oil and gas sector, they are used for shafts, valve bodies, flanges, and piping systems that come into contact with seawater and harsh chemicals. Chemical processing plants rely on them for reactors, heat exchangers, and pipelines that handle corrosive media. The marine industry utilizes these hollow bars in offshore platforms, desalination plants, and seawater systems. They also find applications in petrochemical plants, power generation equipment, and heavy machinery, providing reliable performance across the board.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
