Starc Metals stands out as a top-notch manufacturer and supplier of Duplex Steel Forgings right here in Canberra, Australia. We take pride in offering premium-grade duplex stainless steel products that are engineered for remarkable strength, toughness, and resistance to corrosion. Our duplex steel forgings are crafted using cutting-edge forging techniques, ensuring they boast superior mechanical integrity, precise dimensions, and a fantastic surface finish. At Starc Metals, we deliver high-quality forged components that are built to perform reliably, even in high-pressure and corrosive environments. This makes them perfect for industries like oil & gas, marine, chemical, and power generation.
When it comes to the composition of Duplex Steel Forgings, you’ll typically find 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 austenite and ferrite gives the alloy double the strength of standard austenitic stainless steels. Duplex steel showcases a tensile strength of about 620–880 MPa, along with excellent yield strength and impressive resistance to pitting, crevice corrosion, and stress corrosion cracking. Plus, it offers good weldability and toughness, even in tough environments and high temperatures.

Verify duplex steel forgings' quality by checking certifications, such as ASTM or ISO standards, conducting material testing (e.g., tensile, hardness, corrosion resistance), and inspecting for consistent dimensions, surface finish, and proper labeling.
Yes, duplex steel forgings are highly resistant to corrosion due to their unique blend of austenitic and ferritic microstructures, providing excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.
The maximum operating temperature for duplex steel forgings typically ranges from 250°C to 300°C (482°F to 572°F), depending on the specific grade and application, to maintain optimal mechanical properties.
Duplex Steel Forgings are commonly found in pressure vessels, valves, flanges, pump shafts, and marine hardware. They’re also used in heat exchangers, offshore platforms, and chemical process equipment where strength and corrosion resistance are absolutely essential. The combination of high mechanical performance and exceptional corrosion protection makes duplex steel the go-to choice for environments that face chlorides and aggressive chemicals. With Starc Metals’ Duplex Steel Forgings, you can count on long-term reliability, durability, and efficiency, providing solid solutions for even the most demanding industrial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
