Stainless Steel 446 Bars are a type of ferritic stainless steel characterized by a high chromium content, usually between 23–27%. This composition grants them exceptional resistance to oxidation and scaling, even at high temperatures. The low carbon content enhances their weldability and structural stability, while the lack of nickel boosts their resistance to sulfur-rich environments. In terms of mechanical properties, SS 446 bars demonstrate good tensile strength, moderate hardness, and excellent creep resistance. These attributes make them ideal for continuous use in high-temperature and corrosive settings without a significant drop in mechanical integrity.
