Stainless Steel 446 Tubing is made from a high-chromium ferritic stainless steel alloy that contains up to 27% chromium, which gives it outstanding oxidation and corrosion resistance at elevated temperatures. It boasts good mechanical properties, including moderate tensile strength, excellent thermal stability, and strong resistance to scaling and carburization. While it may not be as ductile as austenitic grades, 446 maintains its structural integrity even under extreme heat and thermal cycling. Its ferritic structure enhances its resistance to sulfurous environments, making it a great choice for demanding applications where heat resistance and longevity are crucial.
