Maduka Metals, a well-respected manufacturer and supplier located in Abuja, Nigeria, specializes in providing top-notch Stainless Steel 446 Hex Bars. Known for their exceptional heat resistance and oxidation stability, these bars are meticulously crafted using cutting-edge manufacturing technology. Maduka Metals guarantees that each product adheres to strict quality standards, making them perfect for applications that demand durability and high-temperature strength. With a strong focus on customer satisfaction and excellence, the company delivers Stainless Steel 446 Hex Bars that ensure consistent performance, reliability, and a long service life across various industrial settings.
Stainless Steel 446 Hex Bar is mainly made up of iron, along with 23–27% chromium, small amounts of manganese, silicon, and trace elements. This ferritic stainless steel boasts remarkable resistance to oxidation, sulfidation, and corrosion, particularly in high-temperature operations. Mechanically, it offers moderate tensile strength, good ductility, and excellent scaling resistance up to 1100°C. Its low carbon content reduces carbide precipitation, which enhances weldability and structural stability under thermal stress. This unique blend of properties makes it an ideal choice for heat-intensive and corrosive environments.

SS 446 Hex Bars offer excellent corrosion resistance, high strength, and durability, making them ideal for harsh industrial environments. Their resistance to oxidation and high-temperature stability ensure reliability in applications like heat exchangers, chemical processing, and petrochemical industries.
SS 446 Hex Bar has superior high-temperature strength and excellent resistance to oxidation compared to other stainless steel alloys like SS 304 or SS 316. Its enhanced durability and corrosion resistance make it ideal for high-stress environments, such as heat exchangers, where other alloys may degrade or weaken over time.
Common machining techniques for SS 446 Hex Bars include turning, milling, drilling, and grinding. Challenges include its high hardness and tendency to work-harden, which can lead to tool wear. Proper lubrication and slower cutting speeds are necessary to maintain tool life and achieve smooth, accurate finishes.
Stainless Steel 446 Hex Bars find extensive use in industries like power generation, chemical processing, and metallurgy. They are perfect for fabricating furnace parts, heat exchanger tubes, kiln linings, and boiler components. Additionally, they are utilized in the production of radiant tubes, burner nozzles, and conveyor belts that operate under high temperatures. Their ability to resist scaling and oxidation makes them a fantastic option for environments exposed to hot gases and corrosive media, ensuring reliability and long-lasting performance in demanding industrial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
