Dhruv Metals is a reliable supplier and manufacturer of Duplex Steel Forgings in Hyderabad, India. They offer forged components that excel in strength, corrosion resistance, and durability. Using top-quality Duplex stainless steel grades like S31803 and S32205, these forgings are precisely produced for industries that operate in corrosive and high-stress settings. The forging process improves the microstructure and enhances mechanical properties, making them appropriate for pressure-retaining parts. Dhruv Metals ensures compliance with ASTM A182 and other international standards, delivering Duplex Steel Forgings with excellent surface finish, precise dimensions, and metallurgical integrity for critical applications.
Duplex Steel Forgings usually consist of 22% chromium, 5 to 6% nickel, 3% molybdenum, and a controlled amount of nitrogen. This alloy offers tensile strength between 620 and 800 MPa and yield strength around 450 to 550 MPa. The structure features a balanced mix of ferrite and austenite, providing great resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. These forgings maintain toughness at low temperatures and have high fatigue resistance. Their chemical and mechanical stability makes them suitable for demanding structural applications in corrosive environments and high-pressure systems.

Verify duplex steel forgings' quality by checking certifications, such as ASTM or ISO standards, conducting material testing (e.g., tensile, hardness, corrosion resistance), and inspecting for consistent dimensions, surface finish, and proper labeling.
Yes, duplex steel forgings are highly resistant to corrosion due to their unique blend of austenitic and ferritic microstructures, providing excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.
The maximum operating temperature for duplex steel forgings typically ranges from 250°C to 300°C (482°F to 572°F), depending on the specific grade and application, to maintain optimal mechanical properties.
Duplex Steel Forgings are widely utilized in pressure vessels, flanges, pipe fittings, valves, and pumps within the oil and gas, petrochemical, and marine industries. Their corrosion resistance and mechanical strength make them ideal for chemical processing, seawater piping systems, and desalination plants. These forgings are also used in subsea equipment, paper mills, heat exchangers, and wastewater treatment facilities. Dhruv Metals provides Duplex Steel Forgings tailored to specific needs, ensuring high fatigue strength and corrosion protection for components subjected to extreme conditions and cyclic loads.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
