Stainless Steel 446 Flat Bar is primarily used in high-temperature and highly corrosive environments, such as industrial furnaces, heat exchangers, thermal oxidizers, and marine applications, due to its exceptional resistance to oxidation, scaling, and chloride stress corrosion.
Stainless Steel 446 Flat Bar contains approximately 23-27% chromium, 0.2% carbon, up to 1.5% manganese, 1.0% silicon, 0.04% sulfur, and trace amounts of nickel, phosphorus, and molybdenum, offering excellent oxidation and corrosion resistance in extreme environments.
Yes, Stainless Steel 446 Flat Bar is highly suitable for high-temperature applications due to its excellent oxidation resistance and ability to withstand temperatures up to 1100°C (2012°F), making it ideal for furnace components, heat exchangers, and thermal oxidizers.
Stainless Steel 446 flat bars are highly used in high-temperature and corrosive environments. It is excellent in oxidation resistance. Some common applications of the material include furnace parts, heat exchangers, boilers, and chimneys where thermal expansion and oxidation resistances are of utmost importance. It is also used in the petrochemical, aerospace, and power generation industries. The alloy with such high strength and tensile strength at elevated temperature is ideal for components being exposed to extreme heat, as well as corrosive gases. Stainless Steel 446 is also used in chemical processing equipment and automobile parts manufacture.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
