Rupal Metals is a prominent Delhi-based manufacturer and supplier of high-quality Duplex Steel S32205 Forgings. Known for providing high-grade products, Rupal Metals serves various industries with precision-engineered forgings that comply with international standards. Our Duplex Steel S32205 forgings are prepared through state-of-the-art technology and rigorous quality checks to maintain durability, corrosion resistance, and mechanical strength. Being dedicated to on-time delivery and customer satisfaction, Rupal Metals is an exemplary choice as a client partner for receiving strong and reliable duplex steel forgings as per industrial specifications in India and internationally.
Duplex Steel S32205 is a balanced structure of 22% chromium, 5-6% nickel, 3% molybdenum, and minor components of nitrogen, manganese, and copper. Its composition makes it stronger and resistant to corrosion. The steel has great mechanical properties, such as tensile strength of about 620-850 MPa and yield strength of around 450 MPa. The duplex microstructure gives it high toughness, good weldability, and excellent resistance to stress corrosion cracking and pitting and is therefore great for harsh industrial use when both strength and durability are needed.

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 application in industries where great strength and corrosion resistance are needed. Typical uses include chemical processing, gas and oil, offshore environments, and pulp and paper production. It is well suited for pressure vessels, valves, pumps, heat exchangers, and structural elements that are subject to aggressive environments. Due to the alloy’s superior resistance to chloride stress corrosion cracking and pitting, it is a first choice for seawater exposure and for aggressive chemical conditions. Its high mechanical properties and strength guarantee long service life, low maintenance costs, and improved safety for important industrial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
