Located in Amman, Jordan, Sabra Metals is a trusted manufacturer and supplier of Stainless Steel 446 Hollow Bars, specifically designed for industries that require exceptional heat and oxidation resistance. Crafted from high-purity ferritic stainless steel, these hollow bars boast impressive dimensional accuracy, consistent wall thickness, and a top-notch surface finish. Sabra Metals adheres to rigorous quality control measures and international standards to guarantee reliable mechanical performance and a long lifespan. With robust supply capabilities throughout the Middle East and beyond, the company provides SS 446 Hollow Bars that are ideal for critical industrial and engineering applications.
Stainless Steel 446 Hollow Bar is a high-chromium ferritic stainless steel that contains around 23–27% chromium, along with very low carbon content to boost oxidation resistance. The elevated chromium levels offer remarkable protection against scaling and corrosion, even at high temperatures. In terms of mechanical properties, SS 446 delivers good tensile strength, moderate yield strength, and excellent thermal stability. Although it has lower ductility compared to austenitic grades, it reliably withstands continuous exposure to high temperatures while maintaining its structural integrity in harsh environments.

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 high-temperature and oxidation-sensitive applications where standard stainless steels might not hold up. They are commonly utilized in furnace components, radiant tubes, heat exchangers, kiln linings, and equipment for petrochemical processing. Additionally, these hollow bars are employed in power plants, thermal processing units, and industrial burners due to their remarkable ability to endure extreme heat without scaling. Furthermore, SS 446 hollow bars are perfect for structural components in chemical plants and refineries, where resistance to corrosive gases and thermal cycling is crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
