Nestled in the heart of Kinshasa, Sadiki Metals has built a reputation as a trusted partner for industry, providing robust materials that stand up to the unique demands of our region. We take pride in offering the Stainless Steel 446 Flat Bar, a product specifically chosen for its exceptional resilience. This grade is engineered to perform where others might falter, making it an ideal choice for projects requiring long-term durability and resistance to the elements, supporting the growth and infrastructure of Congo and beyond.
The strength of Stainless Steel 446 lies in its high chromium content, typically around 23%, which gives it outstanding resistance to oxidation and scaling at elevated temperatures. This composition allows it to retain its strength and resist corrosion in challenging environments, particularly where sulfurous atmospheres are present. It’s a ferritic grade, meaning it possesses a magnetic quality and offers good mechanical properties, including impressive stress rupture and creep resistance, making it a solid, reliable choice for high-heat applications.

Stainless Steel 446 Flat Bar is primarily used in high-temperature and highly corrosive environments, such as industrial furnaces, heat exchangers, thermal oxidizers, and marine applications, due to its exceptional resistance to oxidation, scaling, and chloride stress corrosion.
Stainless Steel 446 Flat Bar contains approximately 23-27% chromium, 0.2% carbon, up to 1.5% manganese, 1.0% silicon, 0.04% sulfur, and trace amounts of nickel, phosphorus, and molybdenum, offering excellent oxidation and corrosion resistance in extreme environments.
Yes, Stainless Steel 446 Flat Bar is highly suitable for high-temperature applications due to its excellent oxidation resistance and ability to withstand temperatures up to 1100°C (2012°F), making it ideal for furnace components, heat exchangers, and thermal oxidizers.
You’ll often find the 446 Flat Bar hard at work in situations where heat is a constant factor. It’s a natural fit for components in industrial furnaces, heat treatment equipment, and thermal processing systems. Beyond high-temperature settings, its general corrosion resistance makes it suitable for architectural details in coastal areas, chemical processing components, and even in high-wear applications like mining or agricultural machinery. Essentially, it’s the go-to material when you need a flat bar that can take the heat and stand the test of time.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
