Starc Metals, a leading manufacturer and supplier located in Canberra, Australia, is all about high-quality Super Duplex Steel Flat Bars. These bars are crafted to provide durable and precision-engineered solutions for tough industrial challenges. Known for their remarkable strength, outstanding corrosion resistance, and long-lasting performance, these flat bars are produced using cutting-edge techniques and strict quality control measures. Starc Metals guarantees consistent dimensional accuracy and material reliability in every batch they produce. They cater to various industries, including oil and gas, chemical processing, marine, and petrochemical sectors, offering Super Duplex Steel Flat Bars in a range of sizes, grades, and finishes, all designed to endure extreme environmental and operational conditions.
Super Duplex Steel Flat Bars are made from a well-balanced mix of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen, resulting in a duplex microstructure of austenite and ferrite. This unique composition gives them excellent resistance to corrosion, including pitting, crevice corrosion, and stress corrosion cracking, while also 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 flat bars are known for their exceptional toughness, weldability, and durability, making them perfect for critical and high-performance engineering applications.

Yes, Super Duplex Steel Flat Bars are highly recyclable. Due to their composition and durability, they can be reused in various industries without compromising their properties or performance.
Super Duplex Steel Flat Bars are generally not suitable for cryogenic applications due to their brittleness at extremely low temperatures. Materials like austenitic stainless steel are often preferred for such uses.
Yes, Super Duplex Steel Flat Bars are suitable for underground applications due to their excellent corrosion resistance, especially in harsh, corrosive environments such as soil or groundwater exposure.
Super Duplex Steel Flat Bars are extensively utilized in industries that demand strong, corrosion-resistant, and durable components. In the oil and gas sector, they are commonly used for flanges, supports, structural components, and valve bodies that are exposed to seawater and harsh chemicals. Chemical processing plants rely on them for piping systems, heat exchangers, and reactor components. The marine industry employs Super Duplex Steel Flat Bars in offshore platforms, desalination plants, and seawater applications. Additionally, they are also used in petrochemical plants, power generation equipment, and heavy machinery.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
