Neith Metals, located in Cairo, Egypt, stands out as a top manufacturer and supplier of high-quality stainless steel products, with a particular focus on Stainless Steel 446 Flat Bars. Known for their commitment to providing materials that are not only high-quality but also resistant to corrosion and heat, Neith Metals caters to a diverse array of industrial sectors. Thanks to their state-of-the-art production facilities and rigorous quality control measures, the company guarantees exceptional product reliability and precision. Their Stainless Steel 446 Flat Bars are specifically designed to deliver outstanding oxidation resistance, mechanical strength, and durability, making them perfect for high-temperature and demanding applications in fields like power generation, chemical processing, and thermal engineering.
Stainless Steel 446 Flat Bars are ferritic stainless steel alloys characterized by a high chromium content (ranging from 23% to 27%) and low carbon levels (≤0.20%), along with small amounts of manganese, silicon, and molybdenum. This unique composition grants them remarkable resistance to oxidation, scaling, and high-temperature corrosion. On the mechanical side, they boast a tensile strength of about 550 MPa and a yield strength close to 350 MPa, ensuring stability even under thermal stress. The alloy’s hardness, toughness, and resistance to sulfidation make these flat bars ideal for applications that require reliable performance in extreme heat and corrosive environments.

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.
Stainless Steel 446 Flat Bars find their place in industries where durability and high-temperature resistance are crucial. They are commonly used in furnace components, heat exchangers, boiler parts, kiln sections, and thermal processing equipment. Additionally, they play a vital role in the petrochemical, power generation, and chemical industries for components that are exposed to heat and corrosive gases. The flat bar shape not only allows for easy fabrication but also provides structural strength and versatility. As a result, Stainless Steel 446 Flat Bars are the go-to choice for manufacturing high-performance industrial parts that demand longevity, reliability, and resistance to scaling and oxidation in extreme conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
