Nestled in the heart of Kinshasa, Congo, Sadiki Metals stands as a trusted partner for industry, specializing in the production of high-performance Duplex Steel S32205 forgings. We understand the demanding conditions faced by local and regional projects, which is why we focus on delivering components that offer exceptional strength and reliability. Our commitment is to provide robust solutions that are forged with precision, supporting the growth and durability of the critical sectors that drive progress across the region and beyond.
The strength of Duplex Steel S32205 lies in its balanced composition, primarily a blend of chromium, nickel, molybdenum, and nitrogen. This synergy creates a material with a unique two-phase microstructure, granting it a remarkable combination of high tensile and yield strength, along with excellent toughness. It also possesses outstanding resistance to corrosion, including stress corrosion cracking, making it far more resilient than standard stainless steels, which allows for lighter and more durable designs in challenging environments.

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 are indispensable in sectors where failure is not an option. You will find them at the core of demanding applications such as high-pressure pipelines in the oil and gas industry, robust components for chemical processing plants handling corrosive media, and critical parts for marine and offshore structures exposed to seawater. Their superior strength and corrosion resistance also make them ideal for the pulp and paper industry and in large-scale desalination units, ensuring long-lasting performance and safety in the most aggressive conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
