Welcome to Sadiki Metals, your trusted partner in Kinshasa for robust and reliable industrial materials. We take pride in manufacturing and supplying high-grade stainless steel solutions tailored for the demanding conditions of the Congo and beyond. Our Stainless Steel 446 Hollow Bar is engineered for exceptional performance, offering a superior combination of strength and corrosion resistance that stands up to the most challenging environments, ensuring your projects are built on a foundation of quality and durability.
The strength of our 446 Hollow Bar comes from its specific composition, which includes a high chromium content. This formulation gives it outstanding resistance to oxidation and scaling at elevated temperatures. Mechanically, it is a ferritic stainless steel known for its good ductility and impressive strength, making it a tough and dependable choice for fabrication. This material reliably maintains its integrity even under significant thermal stress.

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.
This particular hollow bar is ideally suited for high-temperature applications where oxidation is a major concern. You will find it performing excellently in furnace parts, heat treatment equipment, and critical components within the power generation industry. Its resilience also makes it a perfect fit for chemical processing environments and architectural elements that must endure harsh weather. Essentially, it’s the go-to material for any project requiring long-lasting performance under intense heat and corrosive conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
