321 stainless steel exhibits good general corrosion resistance, and excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 – 1500°F (427 – 816°C), 321 resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L.
Good oxidation resistance in intermittent service to 900°C and in continuous service to 925°C. These grades perform well in the 425-900°C range, and particularly where subsequent aqueous corrosive conditions are present, they also possess good low-temperature toughness.
Heat temperature range is limited to 950-1120°C and cool rapidly for maximum corrosion resistance, it cannot be hardened by heat treatment.
