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 find extensive use in industries that demand materials capable of enduring high temperatures, corrosive conditions, and oxidation. In the petrochemical and chemical sectors, they are utilized for furnace components, heat exchangers, and piping systems that face extreme temperatures. In marine applications, they serve as engine parts, shafts, and components that come into contact with seawater and harsh environments. In the power generation field, they are essential for turbines, boilers, and exhaust systems. Furthermore, Stainless Steel 446 Flat Bars are also well-suited for industrial machinery and aerospace components.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
