Aung Metals stands out as a top-notch manufacturer and supplier located in Naypyidaw, Myanmar, specializing in high-quality **Super Duplex Steel Round Bars**. Renowned for their precision engineering and unwavering quality, Aung Metals ensures that their round bars meet international standards, delivering exceptional strength, corrosion resistance, and durability. These Super Duplex Steel Round Bars are crafted to excel in tough environments, whether they’re facing chloride exposure, acidic conditions, or high temperatures. Catering to sectors like chemical processing, oil and gas, marine, and power generation, Aung Metals guarantees products that promise long-lasting operational efficiency and top-tier performance.
When it comes to composition, **Super Duplex Steel Round Bars** typically feature around 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, with iron making up the rest. This blend results in impressive mechanical properties, boasting a tensile strength of 800–1000 MPa, yield strength of 550–750 MPa, and an elongation of 25–30%. The alloy is particularly resistant to pitting, crevice corrosion, and stress corrosion cracking in chloride-heavy environments, all while maintaining excellent toughness and stability at higher temperatures.

Yes, Super Duplex Steel Round Bars can withstand moderately high temperatures but are not ideal for prolonged use above 300°C, as this may reduce their corrosion resistance and mechanical properties.
Yes, Super Duplex Steel Round Bars are highly recyclable. Their materials, including chromium, nickel, and molybdenum, can be reused, promoting sustainability and reducing waste in industrial applications.
No, Super Duplex Steel Round Bars typically do not require additional corrosion protection coatings, as their high chromium, molybdenum, and nitrogen content provides excellent inherent corrosion resistance in harsh environments.
These **Super Duplex Steel Round Bars** are extensively utilized in industries that require outstanding corrosion resistance and mechanical strength. They’re perfect for offshore platforms, marine hardware, chemical and petrochemical processing equipment, heat exchangers, and pressure vessels. In the oil and gas sector, you’ll find them in risers, pipelines, valves, and pumps that come into contact with seawater or harsh chemicals. Their impressive strength-to-weight ratio and durability also make them ideal for structural components in power generation, desalination plants, and other industrial applications that demand long-term reliability and performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
