Stainless Steel 446 Pipes are made from high-chromium ferritic stainless steel, primarily consisting of chromium, iron, manganese, silicon, and trace elements. The high chromium content gives these pipes remarkable resistance to oxidation, sulfidation, and scaling at elevated temperatures. SS 446 offers moderate tensile strength, good thermal conductivity, and excellent dimensional stability during thermal cycling. Its ferritic structure enhances resistance to stress corrosion cracking and boosts high-temperature strength. These pipes also retain sufficient toughness and performance in environments frequently exposed to heat, chemicals, and corrosive gases, making them ideal for demanding service conditions.
