Stainless Steel 446 is a ferritic stainless steel characterized by a high chromium content (around 23–27%) and very low carbon levels, which provide remarkable oxidation and corrosion resistance even at elevated temperatures. In terms of mechanics, it boasts moderate tensile strength, good hardness, and exceptional stability in high-heat environments. This alloy maintains its shape under thermal stress and resists scaling, making it perfect for applications that demand both durability and heat resistance. Its unique blend of mechanical performance, corrosion protection, and thermal stability makes Stainless Steel 446 square bars and rods an excellent choice for challenging industrial settings.
