Dhruv Metals is a prominent manufacturer and supplier of Duplex Steel Hex Bars located in Hyderabad, India. These bars are designed for applications that require high mechanical strength and corrosion resistance. Made using quality Duplex stainless steel grades such as UNS S31803 or S32205, the hex bars feature a balanced mix of austenite and ferrite. This dual-phase structure improves resistance to stress corrosion cracking, pitting, and erosion. Dhruv Metals guarantees that each hex bar meets ASTM A276 and other international standards, delivering materials with excellent accuracy, smooth surface, and reliable performance for various structural and mechanical uses.
Duplex Steel Hex Bars typically contain 22% chromium, 5 to 6% nickel, 3% molybdenum, and nitrogen for improved strength and corrosion resistance. The combination of austenitic and ferritic phases results in high tensile strength (620 to 800 MPa) and yield strength (450 to 550 MPa), which is about double that of standard austenitic stainless steels. Elongation is around 25%, and the bars exhibit great toughness at both high and low temperatures. Duplex steels also resist chloride-induced stress corrosion and provide excellent fatigue strength, making them suitable for harsh marine and chemical processing settings.

Yes, Duplex Steel Hex Bars are fully recyclable. They can be melted down and reused without losing their essential properties, making them an environmentally sustainable option for various applications.
Duplex Steel Hex Bars have inherent corrosion resistance due to their composition. However, in highly aggressive environments, additional coatings or treatments may be necessary to enhance their longevity and performance.
To choose the right Duplex Steel Hex Bar, consider factors such as mechanical strength, corrosion resistance, temperature conditions, and compatibility with your application’s specific industry standards and environmental factors.
Duplex Steel Hex Bars are commonly used in oil and gas exploration, offshore drilling platforms, heat exchangers, and pressure vessels. Their high strength and corrosion resistance make them perfect for pipelines, subsea equipment, structural supports, fasteners, and valves. In marine environments, they are utilized in propeller shafts, seawater cooling systems, and ballast water systems. They are also applied in the paper and pulp industry, desalination plants, and wastewater treatment facilities. Dhruv Metals provides Duplex Steel Hex Bars that meet the highest reliability standards, ensuring superior performance in environments with high mechanical stress and corrosion.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
