Stainless steel 446 is a ferritic stainless steel with a very high chromium content, typically around 23–27%, which provides exceptional resistance to oxidation and scaling at elevated temperatures. The alloy contains low carbon levels, improving stability and reducing the risk of carbide precipitation. It offers good tensile strength, excellent resistance to thermal fatigue, and strong performance in high-heat environments. While ductility is lower than austenitic grades, stainless steel 446 maintains structural integrity and corrosion resistance under extreme temperature conditions.
