Starc Metals, based in Canberra, Australia, is a top-notch manufacturer and supplier that specializes in high-quality Super Duplex Steel Hex Bars. These bars are designed to deliver robust and precision-engineered solutions for tough industrial applications. Renowned for their incredible strength, outstanding corrosion resistance, and long-lasting durability, Starc Metals ensures that their hex bars are crafted using advanced techniques and strict quality control measures, guaranteeing consistent performance and precise dimensions. They cater to various industries, including oil and gas, chemical processing, marine, and petrochemical sectors, offering Super Duplex Steel Hex Bars in a range of sizes, grades, and finishes. The components are built to endure extreme conditions while providing reliable, long-term performance.
Super Duplex Steel Hex Bars are made from a carefully balanced blend of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen, which creates a duplex microstructure of austenite and ferrite. This unique composition gives them exceptional 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 hex bars are not only tough but also easy to weld and incredibly durable, making them perfect for critical applications in harsh and corrosive environments.

Yes, Super Duplex Steel Hex Bars are magnetic due to their mixed microstructure of austenite and ferrite, which gives them magnetic properties, though they are less magnetic than ferritic steels.
Yes, Super Duplex Steel Hex Bars are suitable for hygienic and sanitary applications due to their corrosion resistance, durability, and ease of cleaning, making them ideal for industries like food processing and pharmaceuticals.
Super Duplex Steel Hex Bars are less susceptible to galvanic corrosion compared to other materials due to their high corrosion resistance. However, they may still experience galvanic corrosion when in contact with less resistant metals.
In industries that require corrosion-resistant, high-strength, and durable components, Super Duplex Steel Hex Bars are widely used. In the oil and gas sector, they are utilized for valves, fasteners, shafts, and flanges that are exposed to seawater and aggressive chemicals. Chemical processing plants incorporate them into reactors, heat exchangers, and piping systems. The marine industry relies on Super Duplex Steel Hex Bars for offshore platforms, desalination equipment, and seawater applications. Additionally, they are essential in petrochemical plants, power generation systems, and heavy machinery, providing reliable solutions for demanding environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
