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.
Stainless Steel 446 Hollow Bars find extensive use in industries that demand high-temperature resistance, corrosion protection, and mechanical reliability. They are particularly suited for furnace components, burner assemblies, heat exchangers, and equipment used in high-temperature chemical processing. In the power generation sector, these hollow bars are utilized in boiler structures, superheater supports, and ash-handling systems, thanks to their ability to endure extreme thermal conditions. Additionally, they are employed in petrochemical plants, kiln assemblies, exhaust systems, and incineration units.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
