Aung Metals, a prominent manufacturer and supplier located in Naypyidaw, Myanmar, is well-known for its top-notch Stainless Steel 321 Flat Bars. These bars are crafted to provide outstanding resistance against intergranular corrosion and oxidation, especially at high temperatures. Aung Metals prides itself on delivering precision, durability, and adherence to international standards, thanks to its cutting-edge production techniques and rigorous quality checks. The Stainless Steel 321 Flat Bars come in a variety of sizes and finishes, making them perfect for industries like chemical processing, aerospace, and power generation, where reliability, strength, and long-lasting performance in tough conditions are essential.
These bars are made up of chromium (17–19%), nickel (9–12%), carbon (up to 0.08%), along with manganese, silicon, and stabilizing titanium. The addition of titanium helps prevent carbide precipitation during welding and heat exposure, boosting their corrosion resistance. With a tensile strength of about 515 MPa, a yield strength of around 205 MPa, and an elongation of 40%, they offer impressive mechanical strength, good creep resistance, and thermal stability, making them perfect for extended use in high-temperature settings.

The primary alloying element in Stainless Steel 321 is chromium, typically comprising around 17-19%. Chromium provides corrosion resistance, while titanium is added to improve high-temperature stability and prevent carbide precipitation during welding or prolonged exposure to elevated temperatures.
Stainless Steel 321 is most suitable for temperatures ranging from 800°F to 1500°F (427°C to 815°C). It excels in high-temperature environments due to its titanium stabilization, which prevents carbide precipitation and maintains corrosion resistance under prolonged heat exposure.
Typical dimensions of Stainless Steel 321 flat bars vary, with widths ranging from 20 mm to 150 mm, thicknesses between 3 mm and 50 mm, and lengths up to 6 meters, customizable based on specific requirements.
Stainless Steel 321 Flat Bars are extensively utilized in sectors that demand heat resistance and corrosion protection. They’re ideal for creating components like heat exchangers, furnace parts, pressure vessels, and exhaust systems. These bars also find their place in refineries, petrochemical plants, and thermal processing equipment due to their reliability in high-temperature environments. Furthermore, Stainless Steel 321 Flat Bars are used in aerospace, marine, and food processing industries, where durability, weldability, and resistance to oxidation are vital for efficient and long-lasting operations.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
