Based in the industrious city of Hamilton, New Zealand, Hemi Metals stands as a trusted manufacturer and supplier of high-performance components, specializing in Duplex Steel S32205 Forgings. We understand that in demanding environments, reliability is paramount. Our forged products are crafted with precision and expertise, offering a superior combination of strength and corrosion resistance that you can count on. For industries where failure is not an option, we provide the durable, high-integrity solutions needed to keep operations running smoothly and efficiently.
Duplex Steel S32205 features a unique balanced microstructure of austenite and ferrite, a blend achieved through a composition of chromium, nickel, molybdenum, and nitrogen. This specific chemistry grants it an outstanding mechanical profile, including high tensile and yield strength—significantly greater than standard stainless steels. It also delivers excellent toughness and resistance to stress corrosion cracking, making it a robust material capable of withstanding both heavy loads and aggressive chemical attacks.

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.
The exceptional qualities of S32205 forgings make them indispensable in sectors that push materials to their limits. They are widely used in the oil and gas industry for critical components like valves and pumps, and are equally vital in chemical processing plants handling corrosive substances. You will also find them in marine environments, desalination units, and within high-stress structural applications in pulp and paper production, where their longevity and durability significantly reduce maintenance needs and enhance operational safety.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
