Starc Metals is a well-respected manufacturer and supplier of Duplex Steel Rectangular Bars based in Canberra, Australia. We take pride in offering top-notch duplex stainless steel products that are celebrated for their remarkable strength, corrosion resistance, and durability. Our Duplex Steel Rectangular Bars are crafted using cutting-edge production techniques, ensuring they have precise dimensions, a superior surface finish, and consistent performance. At Starc Metals, we deliver dependable solutions for industries that require materials capable of enduring tough environments, including marine, petrochemical, oil & gas, and power generation sectors.
Typically, the composition of our Duplex Steel Rectangular Bars includes chromium (21–23%), nickel (4.5–6.5%), molybdenum (2.5–3.5%), nitrogen, and a balance of iron. This unique dual-phase microstructure of ferrite and austenite gives the alloy double the strength of standard austenitic stainless steels. With a tensile strength ranging from about 620 to 880 MPa, duplex steel also boasts excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Plus, it offers good weldability and toughness, maintaining stability even in high-pressure and high-temperature situations.

Duplex Steel Rectangular Bars can withstand moderate to high temperatures, but their performance may degrade at temperatures above 300°C (572°F). For extreme heat, other alloys like austenitic stainless steel are preferred.
Yes, Duplex Steel Rectangular Bar are highly recyclable. Their durable composition allows them to be melted down and repurposed in various applications without significant loss of material properties.
Duplex Steel Rectangular Bars have excellent natural corrosion resistance due to their alloy composition. However, in highly aggressive environments, additional coatings or treatments may be recommended for enhanced protection.
Our Duplex Steel Rectangular Bars find extensive use in construction frameworks, marine equipment, chemical processing systems, heat exchangers, pressure vessels, and desalination plants. They’re also perfect for structural supports, shafts, and components that need exceptional mechanical strength and corrosion resistance. The rectangular shape makes them ideal for fabrication, machining, and load-bearing applications. With Starc Metals’ Duplex Steel Rectangular Bars, you get a perfect blend of strength, precision, and long-lasting performance, making them an outstanding choice for industries that operate in challenging environmental and mechanical conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
