Stainless Steel 446 Flanges are manufactured from high-quality ferritic stainless steel with a high chromium content, providing excellent resistance to oxidation, scaling, and corrosion at elevated temperatures. These flanges are particularly suited for demanding heat-intensive environments and can be produced in various types, sizes, pressure ratings, and dimensions to meet specific piping and equipment requirements. The high chromium content gives SS 446 strong resistance to oxidation and scaling during prolonged exposure to high temperatures, while its ferritic structure supports dimensional stability under thermal conditions. Stainless Steel 446 Flanges offer good resistance to sulfur-bearing gases and other aggressive high-temperature atmospheres, making them suitable for furnace equipment, heat treatment systems, petrochemical facilities, and other industrial applications involving elevated temperatures. Their thermal stability, durability, and resistance to oxidation make SS 446 Flanges a practical choice for high-temperature service.
In the annealed condition, Stainless Steel 446 Flanges offer excellent resistance to oxidation, scaling, and corrosion, particularly when exposed to elevated temperatures for extended periods. They are commonly used in furnace equipment, heat treatment plants, petrochemical processing, power generation, industrial burners, and high-temperature process systems where resistance to thermal degradation is important. The high chromium content of SS 446 provides strong protection against oxidation and scaling, while its ferritic structure supports stability during repeated heating and cooling cycles. The grade also performs well in certain sulfur-containing and carburizing atmospheres, making it suitable for specialized high-temperature applications. With good thermal stability, durability, and resistance to oxidation and scaling, Stainless Steel 446 Flanges are a suitable option for demanding piping and equipment connections operating under elevated-temperature conditions.
Stainless Steel 446 Flanges are primarily made from iron and a high proportion of chromium, along with carefully controlled amounts of other alloying elements. The elevated chromium content gives the material strong resistance to oxidation, scaling, and corrosion at high temperatures. Its ferritic structure also supports stable performance in demanding thermal environments. This combination of composition and properties makes SS 446 Flanges suitable for applications where resistance to prolonged heat and oxidation is an important requirement.
