Duplex 2205 Round Bar Manufacturer, Duplex 2205 Round Bar, Duplex 2205 Round Bar in India, Duplex 2205 Round Bar in Mumbai
Duplex 2205 Round Bar is a widely used duplex stainless steel alloy known for its high strength and excellent corrosion resistance, particularly in chloride-rich and marine environments. Composed primarily of chromium, nickel, and molybdenum, Duplex 2205 (UNS S32205/S31803) exhibits a mixed microstructure of austenite and ferrite, which offers a balanced combination of strength and corrosion resistance. Labdhi Metals, a prominent manufacturer, stockist, and exporter, offers high-quality Duplex 2205 round bars that cater to critical industries such as chemical processing, oil & gas, marine, and pulp & paper.
As a manufacturer, Labdhi Metals produces Duplex 2205 round bars using advanced metallurgical processes and quality control systems. These bars are precision-engineered to meet international standards such as ASTM A276 and ASTM A479. They exhibit twice the strength of conventional austenitic stainless steels like 304 and 316, while also offering superior resistance to pitting, crevice corrosion, and stress corrosion cracking. Duplex 2205 is especially suitable for applications where both mechanical strength and corrosion resistance are essential.
As a leading stockist, Labdhi Metals maintains a comprehensive inventory of Duplex 2205 round bars in a wide range of sizes, diameters, and lengths. The bars are available in finishes such as black, bright, polished, and rough turned, and are stored under controlled conditions to preserve their quality. Labdhi Metals also provides value-added services such as cutting, machining, and testing to meet the custom requirements of various industrial applications.
As a global exporter, Labdhi Metals ships Duplex 2205 round bars to several countries across Asia, Europe, the Middle East, and the Americas. Each bar is supplied with complete documentation, including mill test certificates and third-party inspection reports, ensuring traceability and compliance with quality standards. Labdhi Metals has built a reputation for prompt delivery, reliable service, and technical support, making it a preferred supplier in the international market.
