Aung Metals is a well-respected manufacturer and supplier located in Naypyidaw, Myanmar, specializing in high-quality **Super Duplex Steel Flat Bars**. With a reputation for precision engineering and rigorous quality control, Aung Metals crafts flat bars that offer remarkable strength, corrosion resistance, and durability. These Super Duplex Steel Flat Bars are engineered to perform reliably in tough industrial settings, especially where they face harsh conditions like chloride exposure, acidic environments, or high temperatures. Catering to industries such as chemical processing, oil and gas, marine, and power generation, Aung Metals guarantees products that adhere to international standards, ensuring long-term operational efficiency.
Typically, **Super Duplex Steel Flat Bars** consist of about 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, with the remainder being iron. This unique blend provides impressive tensile and yield strength, along with excellent corrosion resistance. The material usually boasts a tensile strength ranging from 800–1000 MPa, yield strength between 550–750 MPa, and an elongation of 25–30%. It shows exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments, while also maintaining toughness and dimensional stability at higher temperatures.

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.
**Super Duplex Steel Flat Bars** find extensive use in industries that require top-notch corrosion resistance and mechanical strength. They’re commonly utilized in chemical and petrochemical processing equipment, heat exchangers, pressure vessels, offshore platforms, and marine hardware. In the oil and gas sector, these bars are essential for pipelines, valves, and pumps that are exposed to seawater or aggressive chemicals. Their impressive strength-to-weight ratio and durability also make them ideal for structural components in power generation plants, desalination systems, and other industrial applications that demand reliable, long-lasting performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
