Aung Metals, a top-notch manufacturer and supplier located in Naypyidaw, Myanmar, proudly presents its high-quality Super Duplex Steel Hollow Bars. These bars are celebrated for their remarkable strength, resistance to corrosion, and long-lasting durability. Crafted with cutting-edge technology and rigorous quality control, they meet international standards with ease. Thanks to a well-balanced microstructure of austenite and ferrite, these Super Duplex Steel Hollow Bars offer outstanding protection against pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. Aung Metals guarantees precise dimensions and a smooth surface finish, making these hollow bars perfect for demanding applications in industries like marine, chemical, oil and gas, and power generation.
The composition of Super Duplex Steel Hollow Bars includes around 25% chromium, 7% nickel, 3.6% molybdenum, along with trace amounts of tungsten, copper, and nitrogen. This unique blend boosts their corrosion resistance and mechanical strength. They boast a tensile strength ranging from 800 to 850 MPa, a yield strength of 550 MPa, and an elongation of about 25%. The duplex structure of the alloy provides exceptional hardness, toughness, and fatigue resistance, ensuring stability even under high pressure, temperature, and corrosive conditions. This makes them ideal for critical and long-lasting industrial applications.

Yes, Super Duplex Steel Hollow Bars can withstand high temperatures due to their excellent strength and corrosion resistance. They are suitable for applications in environments up to around 300°C (572°F), depending on the specific alloy.
Super Duplex Steel Hollow Bars and Rods are manufactured through hot or cold working processes, including extrusion and forging, followed by heat treatment, cold drawing, and precision machining for enhanced strength and corrosion resistance.
Super Duplex Steel Hollow Bars have excellent natural corrosion resistance due to their high chromium and molybdenum content, making additional protective coatings generally unnecessary. However, in highly aggressive environments, coatings may offer extra protection.
Aung Metals’ Super Duplex Steel Hollow Bars find their place in various industries that demand both mechanical strength and corrosion resistance. They’re particularly well-suited for offshore oil and gas drilling, desalination plants, and chemical processing equipment. Their durability and resistance to chloride-induced corrosion make them a go-to choice for marine applications and seawater systems. Additionally, these hollow bars are utilized in heat exchangers, pressure vessels, and instrumentation tubing. Their reliable performance in high-stress, corrosive, and high-temperature environments guarantees a long service life and consistent results in essential engineering operations.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Aung Metals is a leading manufacturer, supplier, and exporter of high-quality bars, rods, and forgings, catering to various industries in Naypyidaw, Myanmar
