Dhruv Metals, a leading manufacturer and supplier located in Hyderabad, India, has built a solid reputation for providing top-notch alloy solutions, including Super Duplex Steel Flat Bars. These flat bars are designed with strength, corrosion resistance, and precision in mind, making them perfect for critical and high-demand applications. Thanks to our cutting-edge production methods and rigorous quality control, Dhruv Metals guarantees that every Super Duplex Steel Flat Bar meets international standards for durability and dimensional accuracy. Industries across various sectors trust our flat bars for their reliable performance, even in the toughest operating conditions, both at home and abroad.
Super Duplex Steel Flat Bars are primarily made up of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen (0.2–0.3%), featuring a balanced microstructure of austenite and ferrite. This unique dual-phase structure provides exceptional resistance to stress corrosion cracking, pitting, and crevice corrosion. The mechanical properties are impressive, boasting a high tensile strength of around 795 MPa, a yield strength of 550 MPa or more, an elongation of about 15%, and outstanding impact toughness. These characteristics, along with excellent weldability and fatigue resistance, make Super Duplex Steel Flat Bars ideal for challenging structural and corrosive environments.

Yes, Super Duplex Steel Flat Bars are highly recyclable. Due to their composition and durability, they can be reused in various industries without compromising their properties or performance.
Super Duplex Steel Flat Bars are generally not suitable for cryogenic applications due to their brittleness at extremely low temperatures. Materials like austenitic stainless steel are often preferred for such uses.
Yes, Super Duplex Steel Flat Bars are suitable for underground applications due to their excellent corrosion resistance, especially in harsh, corrosive environments such as soil or groundwater exposure.
These flat bars find extensive use in applications that demand high strength, excellent corrosion resistance, and structural integrity. They are commonly utilized in offshore oil and gas platforms, desalination plants, chemical processing units, marine environments, and structural components in high-chloride atmospheres. In power generation and heat exchanger systems, they offer long-lasting resistance against aggressive media. Their strength and durability also make them suitable for bridges, load-bearing frameworks, and pressure vessels. Given their exceptional performance in corrosive and mechanically demanding settings, Super Duplex Steel Flat Bars are the go-to choice for industries that need reliable, long-lasting materials.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
