Manila, Philippines-based Isis Metals is a prominent producer and supplier of Duplex Steel Forgings. With a reputation for supplying materials that possess strength, toughness, and corrosion resistance, Isis Metals services exacting industries like oil and gas, marine, and chemical processing. Isis Metals vows to supply products that are of the highest quality of durability, reliability, and performance. Emphasizing precision engineering and quality control, Isis Metals ensures each Duplex Steel Forging is appropriate for high-stakes applications, providing customers with long-life, high-performance solutions that can endure harsh and aggressive operating conditions.
Duplex Steel Forgings have a dual-phase structure of austenite and ferrite with a chemical composition of around 18–28% Chromium, 4–8% Nickel, 2–5% Molybdenum, and traces of Manganese, Silicon, and Nitrogen. The alloy offers a fine balance of strength and corrosion resistance. Mechanical properties are yield strengths of 450–650 MPa, tensile strengths of 620–850 MPa, and elongation of 25–40%. Duplex Steel also possesses excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, and thus it is perfectly suited for application in tough offshore, marine, and chemical processing conditions.

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 find extensive application in those industries where strength, corrosion resistance, and toughness are required. In oil and gas, they are utilized in pipelines, pressure vessels, and offshore platform equipment that are exposed to chloride-rich environments. In the marine industry, forgings are used in propeller shafts, seawater systems, and shipbuilding structures. They are used in the chemical and petrochemical industry in reactors, heat exchangers, valves, and fittings where resistance to aggressive chemicals requires high toughness. In general, Duplex Steel Forgings are best suited to high-performance applications with consistent operation in corrosive and tough environments for energy, marine, and chemical processing industries.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
