Phehlukwayo Metal, a reliable manufacturer and supplier located in Cape Town, South Africa, specializes in top-notch **Stainless Steel 446 Hollow Bars** that are built to withstand extreme heat and resist corrosion. These bars are crafted to excel in high-temperature settings and oxidizing environments. With a commitment to precision manufacturing and strict adherence to international quality standards, Phehlukwayo Metal guarantees consistent strength, durability, and reliability. The Stainless Steel 446 Hollow Bars are perfect for applications that demand superior scaling resistance and structural integrity, making them ideal for furnace components, heat exchangers, and equipment used in chemical processing.
**Stainless Steel 446 Hollow Bar** is a high-chromium ferritic alloy primarily made up of chromium (23–27%), along with trace amounts of nickel, manganese, silicon, carbon (≤0.20%), and iron as the main component. It boasts a tensile strength of around 485 MPa, a yield strength of about 275 MPa, and an elongation of roughly 20%. This alloy is known for its exceptional resistance to oxidation, sulfidation, and scaling at temperatures reaching up to 1100°C. Additionally, it offers great thermal conductivity, stability, and wear resistance, while maintaining moderate ductility and good machinability.

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 corrosive settings where durability and scaling resistance are crucial. Typical applications include furnace linings, burner nozzles, heat exchanger tubes, kiln rollers, and thermal processing equipment. They are also well-suited for power generation, petrochemical facilities, and the metallurgical sector. Thanks to their high chromium content, these bars provide excellent oxidation resistance in both air and combustion gases, while their ferritic structure ensures stability during thermal cycling, promising a long service life and reliable performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
