Isis Metals, a well-respected manufacturer and supplier located in Manila, Philippines, specializes in high-quality Stainless Steel 446 Flat Bars designed for outstanding performance in high-temperature and corrosive settings. Renowned for their exceptional resistance to oxidation and scaling, these flat bars are perfect for industrial applications that involve heat and chemical exposure. Stainless Steel 446 is a ferritic stainless steel known for its impressive resistance to sulfurous gases and oxidation at elevated temperatures. Isis Metals guarantees precision in manufacturing, a superior surface finish, and adherence to international standards, providing durable and reliable SS 446 Flat Bars for various industrial, structural, and mechanical uses.
Stainless Steel 446 Flat Bar is a ferritic stainless steel alloy that contains 23–27% chromium, along with trace amounts of molybdenum, silicon, and manganese, and a maximum of 0.20% carbon. The high chromium content gives it remarkable resistance to oxidation, scaling, and corrosion in hot and sulfurous environments. It boasts a tensile strength of about 485 MPa and excellent creep strength at high temperatures. While it can’t be hardened through heat treatment, SS 446 provides good thermal stability, magnetic properties, and impressive mechanical performance even in extreme heat and corrosive conditions.

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 are commonly utilized in situations that demand resistance to oxidation, corrosion, and thermal fatigue. They are particularly well-suited for furnace parts, heat exchanger components, burner nozzles, boiler tubes, and kiln linings. Additionally, they find applications in the power generation, petrochemical, and chemical processing industries for high-temperature equipment. SS 446 Flat Bars are also ideal for incineration units, exhaust manifolds, and thermal processing systems, thanks to their ability to maintain structural integrity under intense heat. Their durability, cost-effectiveness, and resistance to scaling make them a go-to choice for many 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.
