Isis Metals, a top-notch manufacturer and supplier based in Manila, Philippines, specializes in premium Stainless Steel 446 Rectangular Bars that are engineered for outstanding performance in high-temperature and corrosive settings. Crafted with precision and a commitment to international quality standards, these bars boast remarkable resistance to oxidation, scaling, and sulfidation. Known for its high chromium content, Stainless Steel 446 is a ferritic stainless steel that offers exceptional durability and stability, even in extreme thermal conditions. Isis Metals guarantees accurate dimensions, smooth finishes, and dependable mechanical strength, making these rectangular bars perfect for a variety of industrial and engineering applications.
Stainless Steel 446 Rectangular Bars are ferritic stainless steels that contain 23–27% chromium, along with trace amounts of carbon (≤0.20%), manganese, silicon, and molybdenum. The elevated chromium content ensures excellent oxidation and corrosion resistance at high temperatures. These bars have a tensile strength of around 485 MPa and impressive creep resistance. While SS 446 cannot be hardened through heat treatment, it maintains strong mechanical stability and scaling resistance during prolonged exposure to heat. Additionally, the alloy displays good magnetic properties and reliable structural strength in demanding high-temperature environments.

When selecting Stainless Steel 446 Rectangular Bars, consider factors like temperature resistance, corrosion resistance, and the specific environmental conditions. Additionally, ensure compatibility with the required mechanical properties and fabrication needs.
Stainless Steel 446 Rectangular Bars are not ideal for cryogenic applications due to their reduced toughness at low temperatures. For cryogenic use, materials with better low-temperature properties, like austenitic stainless steels, are recommended.
Stainless Steel 446 Rectangular Bars generally do not require additional corrosion protection coatings due to their inherent high corrosion resistance. However, in highly aggressive environments, coatings may be used for added protection.
Stainless Steel 446 Rectangular Bars find extensive use in industries where heat, oxidation, and corrosion resistance are paramount. They are perfect for creating furnace parts, boiler components, kiln linings, heat exchanger tubes, and burner nozzles. Moreover, these bars are utilized in chemical processing, petrochemical, and power generation sectors for equipment that endures high temperatures and corrosive gases. SS 446 Rectangular Bars are also well-suited for exhaust systems, thermal processing facilities, and incineration applications.
