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 their place in industries that demand high strength and corrosion resistance. In the oil & gas sector, they’re used in subsea equipment, pipelines, flanges, and valves. In marine applications, you’ll find them in ship components, propeller shafts, and seawater systems. The chemical and petrochemical industries rely on them for heat exchangers, reactors, and pressure vessels. Construction projects also benefit from their durability in frameworks and load-bearing applications. Plus, they’re widely utilized in the pulp & paper industries, desalination plants, and food processing equipment. Their ability to withstand harsh conditions makes them a go-to choice across various sectors.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
