Duplex Steel S32205 forgings are available in various sizes, including round, square, and custom shapes. They can range from small to large diameters and lengths, depending on application requirements.
Yes, S32205 Duplex Steel forgings are highly resistant to corrosion, particularly in chloride-rich environments. They offer excellent resistance to pitting, crevice, and stress corrosion cracking, making them ideal for harsh conditions.
The maximum operating temperature for Duplex Steel S32205 forgings is typically around 300°C (572°F). Beyond this, the material's strength and corrosion resistance may degrade due to sensitization and phase changes.
Duplex Steel S32205 Forgings find extensive use in industries that require materials with exceptional strength and corrosion resistance. They’re commonly utilized in the oil and gas sector for subsea pipelines, valves, pumps, and manifolds, where the risk of chloride-induced corrosion is significant. In chemical processing facilities, they serve as pressure vessels, heat exchangers, and reactors. The marine and desalination sectors employ them for shafts, fasteners, and seawater handling systems. Additionally, the power generation and pulp and paper industries depend on them for structural components. The combination of mechanical properties and durability makes these forgings a go-to choice for demanding applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
