Stainless Steel 446 Pipes are high-chromium ferritic stainless steels that contain 23–27% chromium, along with a low carbon content (≤0.20%) and small amounts of manganese, silicon, sulfur, and molybdenum. These pipes are known for their exceptional resistance to oxidation and corrosion, even in extreme temperature conditions. They boast a tensile strength ranging from 485 to 620 MPa, a yield strength of about 275 MPa, and an elongation of roughly 20%. While SS 446 may be less ductile and weldable compared to austenitic grades, it excels in applications involving furnaces and heat treatment, thanks to its good creep resistance and mechanical stability under prolonged thermal stress.

Stainless Steel 446 Pipe Uses

Stainless Steel 446 Pipes are perfect for high-temperature service applications, especially in industrial furnaces, kilns, and heat exchangers, due to their superior resistance to scaling and thermal fatigue. In the petrochemical and refinery sectors, they find use in radiant tubes, reformer tubes, and flue gas systems. SS 446 is also well-suited for power plants, thermal processing equipment, and exhaust systems operating in harsh environments. Furthermore, these pipes are utilized in incinerators, metal smelting, and waste heat recovery systems, where their resistance to oxidation and sulfidation is crucial.
