Maduka Metals is a reputable manufacturer and supplier located in Abuja, Nigeria, known for its top-notch Stainless Steel 446 Hollow Bars. With a solid track record of excellence and dependability, we serve a variety of industrial sectors that need durable and high-temperature-resistant materials. Our Stainless Steel 446 Hollow Bars are crafted using cutting-edge technology and rigorous quality control measures to guarantee outstanding corrosion resistance, thermal stability, and mechanical strength. At Maduka Metals, we are dedicated to providing precision-engineered products that adhere to global standards, offering our clients efficient, cost-effective, and long-lasting solutions for challenging engineering and structural needs.
Stainless Steel 446 Hollow Bar is a high-chromium ferritic alloy that contains about 23–27% chromium, 0.2% carbon, 1.5% manganese, 1% silicon, along with trace amounts of sulfur and phosphorus. This unique composition gives it remarkable resistance to oxidation and scaling at high temperatures. In terms of mechanical properties, it boasts high tensile strength (around 550 MPa), good hardness, and excellent creep resistance. While it may have limited ductility, the alloy retains its structural integrity under thermal stress, making it perfect for applications that face high heat and corrosive conditions.

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 require exceptional heat and corrosion resistance. Typical applications include components for furnaces, burner nozzles, heat exchangers, and kiln liners. They are also utilized in petrochemical plants, power generation systems, and exhaust manifolds where they are exposed to high temperatures and oxidizing gases. Additionally, Stainless Steel 446 Hollow Bars are employed in chemical processing equipment, boiler tubes, and structural frameworks in harsh environments. Their outstanding oxidation resistance and stability make them an excellent choice for long-term service in elevated temperature settings.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
