Aung Metals, a top-notch manufacturer and supplier located in Naypyidaw, Myanmar, specializes in high-quality **Stainless Steel 446 Rectangular Bars**. These bars are celebrated for their remarkable corrosion resistance, impressive strength at high temperatures, and overall durability. Crafted with precision and under strict quality control, they adhere to international standards, ensuring dependable performance even in tough industrial settings. Thanks to their high chromium and low carbon content, 446 stainless steel offers excellent protection against pitting, scaling, and oxidation, even when faced with extreme heat. Aung Metals’ 446 Rectangular Bars find their place in various industries, including chemical, marine, power generation, and high-temperature applications, providing structural integrity, long-lasting reliability, and outstanding operational efficiency.
These Stainless Steel 446 Rectangular Bars are primarily made up of 23–27% chromium, with a carbon content of ≤0.2%, along with trace amounts of manganese, silicon, and molybdenum. This unique composition grants them exceptional corrosion resistance and excellent stability against high-temperature oxidation. They boast impressive mechanical properties, including a tensile strength ranging from 450–650 MPa, yield strength between 200–300 MPa, and an elongation of 20–30%. The material also offers good hardness, toughness, and thermal stability, making it perfect for applications that require both mechanical strength and resistance to high temperatures.

When selecting Stainless Steel 446 Rectangular Bars, consider factors like temperature resistance, corrosion resistance, and the specific environmental conditions. Additionally, ensure compatibility with the required mechanical properties and fabrication needs.
Stainless Steel 446 Rectangular Bars are not ideal for cryogenic applications due to their reduced toughness at low temperatures. For cryogenic use, materials with better low-temperature properties, like austenitic stainless steels, are recommended.
Stainless Steel 446 Rectangular Bars generally do not require additional corrosion protection coatings due to their inherent high corrosion resistance. However, in highly aggressive environments, coatings may be used for added protection.
Aung Metals’ Stainless Steel 446 Rectangular Bars are extensively utilized in industries that demand components capable of withstanding high temperatures and corrosion. They are particularly well-suited for furnace parts, heat exchangers, chimney linings, and gas burners. Moreover, they are employed in chemical processing equipment, boiler components, and marine applications that face harsh and high-temperature conditions. The combination of mechanical strength, high-temperature stability, and corrosion resistance ensures these bars deliver a long service life, reliable performance, and operational efficiency in critical industrial and engineering applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
