Aung Metals, a reputable manufacturer and supplier located in Naypyidaw, Myanmar, specializes in top-notch Super Duplex Steel Rectangular Bars that are engineered for outstanding performance in tough industrial settings. These bars are crafted to offer high strength, exceptional corrosion resistance, and remarkable durability, making them perfect for rigorous engineering tasks. With a commitment to precision and adherence to international standards, Aung Metals guarantees excellent dimensional accuracy and surface quality. The Super Duplex Steel Rectangular Bars are designed to resist pitting, crevice corrosion, and stress corrosion cracking, making them a reliable choice for marine, chemical, petrochemical, and offshore applications that demand long-lasting performance.
These bars are primarily composed of chromium (25%), nickel (7%), molybdenum (3.5%), along with nitrogen, tungsten, and copper, which together create a well-balanced microstructure of austenite and ferrite. This unique composition provides impressive resistance to corrosion caused by chlorides and oxidation. The mechanical properties of these bars are equally impressive, boasting a tensile strength of 800–850 MPa, a yield strength of 550 MPa, and an elongation of about 25%. They also demonstrate remarkable hardness, toughness, and fatigue resistance, ensuring they maintain excellent stability and performance even under extreme pressure and temperature conditions.

When selecting Super Duplex Steel Rectangular Bars, consider factors like corrosion resistance, mechanical strength, operating temperature, application environment, and compliance with industry standards for optimal performance.
Yes, Super Duplex Steel Rectangular Bars can be welded using appropriate techniques such as TIG or MIG welding. However, proper heat control is necessary to maintain their corrosion resistance and mechanical properties.
Super Duplex Steel Rectangular Bars are not ideal for cryogenic applications, as their toughness and ductility may decrease at extremely low temperatures, potentially leading to brittleness in such environments.
Aung Metals’ Super Duplex Steel Rectangular Bars are widely utilized in industries where superior mechanical and corrosion-resistant characteristics are essential. They are commonly found in offshore oil and gas platforms, desalination plants, marine equipment, and chemical processing systems. Additionally, these bars are used in heat exchangers, pressure vessels, and structural components that face high-stress and corrosive environments. Their ability to endure harsh conditions and heavy loads makes them an ideal choice for power generation, pulp and paper processing, and seawater handling systems, guaranteeing durability and reliable operation in every application.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
