So, what exactly are Stainless Steel 446 Sheets and Plates? They’re high-chromium ferritic stainless steels that contain about 23–27% chromium, along with low carbon and trace amounts of manganese and silicon. This unique blend gives them excellent oxidation and corrosion resistance, even at elevated temperatures. They boast a tensile strength of around 485 MPa and a yield strength of about 275 MPa, along with good creep strength and moderate ductility. These characteristics make Stainless Steel 446 an ideal choice for applications that face intense heat, thermal cycling, and sulfur-rich environments.
