Stainless Steel 446 Flat Bar is chiefly employed in high-temperature and severely corrosive settings, including industrial furnaces, heat exchangers, thermal oxidizers, and marine applications, thanks to its outstanding resistance to oxidation, scaling, and chloride stress corrosion.
Stainless Steel 446 Flat Bar consists of roughly 23-27% chromium, 0.2% carbon, as much as 1.5% manganese, 1.0% silicon, 0.04% sulfur, and small quantities of nickel, phosphorus, and molybdenum, providing outstanding oxidation and corrosion resistance under extreme conditions.
Yes,Stainless Steel 446 Flat Bar is exceptionally well-suited for high-temperature applications thanks to its outstanding oxidation resistance and its capacity to endure temperatures reaching 1100°C (2012°F), which makes it perfect for furnace components, heat exchangers, and thermal oxidizers.
Owing to its exceptional resistance to heat and corrosion, Stainless Steel 446 Flat Bar sees broad use across many industries. It is especially fitting for applications such as furnace parts, heat exchangers, boiler tubes, and kiln linings, where withstanding high-temperature oxidation is critical. Within the chemical and petrochemical sectors, it serves to handle acidic and corrosive substances. On top of that, it appears in power plants, cement industries, and exhaust systems thanks to its durability and dimensional stability. The material’s strength, ease of fabrication, and scaling resistance make it an excellent option for both structural and thermal processing uses.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
