Aung Metals, based in Naypyidaw, Myanmar, has earned a solid reputation as a reliable manufacturer and supplier of top-notch stainless steel products, with a particular focus on Duplex Steel Forgings. With a wealth of experience in precision manufacturing and cutting-edge metallurgy, Aung Metals provides robust and corrosion-resistant forged components suitable for a wide range of industrial uses. Duplex Steel Forgings uniquely blend the strength of ferritic and austenitic stainless steels, delivering outstanding mechanical performance and resilience in tough environments. Dedicated to upholding international quality standards, reliability, and customer satisfaction, Aung Metals serves various sectors, including oil and gas, chemical processing, marine, construction, and power generation, both in Myanmar and around the globe.
These Duplex Steel Forgings typically consist of about 22% chromium, 5% nickel, 3% molybdenum, along with trace amounts of nitrogen, manganese, and silicon. This well-balanced composition grants them exceptional corrosion resistance and impressive mechanical strength. The material boasts a yield strength ranging from 450 to 550 MPa and a tensile strength between 620 and 850 MPa, with hardness levels usually falling between 280 and 330 HB. Its unique dual-phase microstructure—comprising roughly equal parts ferrite and austenite—ensures remarkable toughness, fatigue resistance, and dimensional stability, even under extreme pressure and temperature conditions.

Verify duplex steel forgings' quality by checking certifications, such as ASTM or ISO standards, conducting material testing (e.g., tensile, hardness, corrosion resistance), and inspecting for consistent dimensions, surface finish, and proper labeling.
Yes, duplex steel forgings are highly resistant to corrosion due to their unique blend of austenitic and ferritic microstructures, providing excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.
The maximum operating temperature for duplex steel forgings typically ranges from 250°C to 300°C (482°F to 572°F), depending on the specific grade and application, to maintain optimal mechanical properties.
Duplex Steel Forgings find extensive application in industries that demand high strength, durability, and corrosion resistance. They are perfect for crafting components like flanges, shafts, rings, and valve bodies in sectors such as oil and gas, petrochemical, marine, and desalination. These forgings excel in chloride-rich or acidic environments, significantly minimizing the chances of pitting and stress corrosion cracking. Moreover, they are utilized in heat exchangers, pressure vessels, and structural applications where superior mechanical performance is crucial. With Duplex Steel Forgings, you can count on long-lasting reliability, lower maintenance needs, and cost-effectiveness in challenging industrial operations.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
