  • Stainless Steel 446

    DIN :X8Cr28    TOCT:15X25T

    ASTM/AISI:446    SS14:2322

    Stainless Steel 446


    446 stainless steel is highly resistant to high temperature corrosion. Compared with 445, it has high Cr, low carbon and Mo added to ensure high corrosion resistance. No peeling scale is produced below 1082 ° C for use in the combustion chamber. Stainless steel for exterior materials for large public buildings in coastal and industrial areas.


    1) high corrosion resistance;
    2) weather resistance;
    3) high intensity;
    4) Magnetic;
    5) It cannot be hardened by heat treatment.
