Starc Metals, based in Canberra, Australia, is a top-notch manufacturer and supplier that focuses on high-quality Super Duplex Steel Forgings. These products are crafted to deliver durable and precision-engineered solutions for tough industrial applications. Renowned for their remarkable strength, outstanding corrosion resistance, and long-lasting performance, these forgings are produced using cutting-edge techniques and rigorous quality control to guarantee consistent accuracy and reliability. Starc Metals caters to various industries, including oil and gas, chemical processing, marine, and petrochemical sectors, offering Super Duplex Steel Forgings in a range of sizes, grades, and finishes. The company ensures that their components are built to perform reliably, even in extreme operational and environmental conditions.
Super Duplex Steel Forgings are made from a carefully balanced alloy that includes chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen, resulting in a unique duplex microstructure of ferrite and austenite. This specific composition gives them excellent resistance to corrosion, including pitting, crevice corrosion, and stress corrosion cracking, all while maintaining impressive mechanical strength. Typical mechanical properties feature a tensile strength of 750–900 MPa, yield strength of 550–700 MPa, and elongation of 25–30%. These forgings are known for their superior toughness, weldability, and durability, making them perfect for high-performance and critical applications in harsh environments.

To verify the quality of Super Duplex Steel forgings, check for certifications like ASTM, ASME, or ISO standards. Conduct tests such as mechanical property testing, chemical composition analysis, and non-destructive testing (NDT) like ultrasonic or magnetic particle inspections.
Compatible welding processes for Super Duplex Steel forgings include Tungsten Inert Gas (TIG), Metal Inert Gas (MIG), Shielded Metal Arc Welding (SMAW), and Submerged Arc Welding (SAW), using appropriate filler materials.
Super Duplex Steel forgings are governed by standards such as ASTM A182, ASTM A240, ASME SA-182, ASME SA-240, and EN 10088-3, which define material properties, chemical composition, and mechanical requirements.
Super Duplex Steel Forgings are extensively utilized in industries that require high-strength, corrosion-resistant, and long-lasting components. In the oil and gas sector, they are commonly found in valves, flanges, shafts, and fasteners that are exposed to seawater and aggressive chemicals. Chemical processing plants use them in piping systems, reactors, and heat exchangers. The marine industry relies on these forgings for offshore platforms, desalination equipment, and seawater applications. Additionally, they are also used in petrochemical plants, power generation systems, and heavy machinery, ensuring reliable performance 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.
