Aung Metals, a reputable manufacturer and supplier located in Naypyidaw, Myanmar, is dedicated to crafting top-notch Super Duplex Steel Bright Bars. These bars are celebrated for their remarkable strength, outstanding resistance to corrosion, and exceptional surface finish. Produced with cutting-edge technology and precise machining, they adhere to international quality standards, making them perfect for challenging industrial settings. Thanks to their unique dual-phase microstructure of austenite and ferrite, Super Duplex Steel Bright Bars provide impressive protection against pitting, crevice corrosion, and chloride stress corrosion cracking, which makes them versatile for various engineering and structural uses.
These bars are made up of roughly 25% chromium, 7% nickel, and 3.6% molybdenum, with added copper, tungsten, and nitrogen to boost their strength and corrosion resistance. They boast a tensile strength of about 800–850 MPa, a yield strength of 550 MPa, and an elongation of around 25%. The duplex structure guarantees excellent toughness, hardness, and fatigue resistance, even in extreme pressures and temperatures, ensuring long-lasting reliability and durability in demanding industrial conditions.

The hardness of Super Duplex Steel Bright Bars typically ranges between 250-300 HB (Hardness Brinell), depending on the specific grade and heat treatment, offering excellent strength and resistance to wear and corrosion.
Yes, Super Duplex Steel Bright Bars can be recycled after use. Their high chromium and nickel content makes them highly recyclable, contributing to sustainability and reducing the need for new raw materials.
Super Duplex Steel Bright Bars are highly resistant to corrosion due to their high chromium and molybdenum content. However, in highly aggressive environments, additional coatings may be applied for extra protection.
Aung Metals’ Super Duplex Steel Bright Bars are extensively utilized in industries that require high mechanical strength and corrosion resistance. They are particularly well-suited for marine engineering, offshore oil and gas platforms, desalination plants, and chemical processing systems. These bars also find applications in heat exchangers, pumps, shafts, fasteners, and pressure vessels. With their superior surface finish and precise dimensions, they are ideal for both structural and decorative uses. Their excellent resistance to stress corrosion and pitting ensures consistent performance in aggressive and high-temperature environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
