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 extensively utilized in industries where materials must withstand extreme heat and oxidation. They are particularly well-suited for furnace components, burner nozzles, kiln linings, heat exchangers, and thermal processing equipment. Additionally, these bars are essential in power generation, chemical processing, and petrochemical sectors where high-temperature corrosion resistance is crucial. Their durability and capacity to retain strength and integrity under fluctuating temperatures make Stainless Steel 446 Flat Bars ideal for long-term use in challenging industrial, engineering, and environmental conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
