Stainless Steel 446 is a ferritic stainless steel characterized by a high chromium content (around 23–27%) and very low carbon, which is engineered for excellent oxidation and corrosion resistance at elevated temperatures. In terms of mechanical properties, it provides moderate tensile strength, good hardness, and remarkable stability in high-temperature settings. This alloy maintains its structural integrity under thermal stress and resists scaling, making it suitable for applications that demand both durability and heat resistance. Its unique blend of corrosion protection, thermal stability, and mechanical performance makes Stainless Steel 446 hollow bars an excellent choice for challenging industrial environments.

SS 446 hollow bars typically contain 23-27% chromium, 1-2% silicon, 0.75% manganese, and small amounts of carbon, phosphorus, sulfur, and nickel, providing excellent resistance to high-temperature oxidation and corrosion.
Key benefits of SS 446 hollow bars include excellent high-temperature oxidation resistance, superior corrosion resistance, durability in harsh environments, and strength at elevated temperatures, making them ideal for furnace and chemical processing applications.
These hollow bars are extensively utilized in industries that require high-temperature corrosion resistance and durability. They are perfect for crafting furnace components, heat exchangers, boiler parts, and chemical processing equipment that face aggressive conditions. In marine and industrial settings, 446 hollow bars are employed for structural components and high-temperature piping, where long-term stability and corrosion resistance are crucial. Their ability to resist scaling and maintain mechanical integrity under thermal stress makes them a go-to option for engineers looking for reliable, long-lasting, and high-performance materials.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
