Anucha Metals stands out as a reliable manufacturer and supplier of Duplex Steel S32205 Forgings right in the heart of Bangkok, Thailand. They pride themselves on delivering top-notch forged components that not only boast high strength but also exceptional corrosion resistance. The S32205 duplex steel is known for its unique dual-phase structure, which combines austenite and ferrite, resulting in impressive mechanical properties, resistance to stress corrosion cracking, and remarkable performance even in harsh, chloride-rich environments. Anucha Metals is committed to ensuring that every forging adheres to international quality standards, providing precise dimensions, a flawless surface finish, and consistent durability for even the most demanding industrial applications.
When it comes to composition, Duplex Steel S32205 Forgings are primarily made up of chromium, nickel, and molybdenum, with added nitrogen and manganese to boost corrosion resistance and mechanical strength. This blend gives the material high tensile and yield strength, excellent toughness, and strong resistance to pitting and crevice corrosion. The duplex structure also enhances fatigue resistance and weldability, making it ideal for heavy-duty and high-stress applications.

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.
These forgings find extensive use in chemical and petrochemical plants, heat exchangers, pressure vessels, pumps, valves, desalination plants, and marine equipment, where both strength and corrosion resistance are crucial. Their blend of durability, reliability, and performance in aggressive environments makes Duplex Steel S32205 forgings a top choice for critical engineering applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
