321 has excellent corrosion resistance equivalent to type 302 or 304 in the annealed condition and superior if a weldment in these grades has not been post-weld annealed or if the application involves service in the 800°F – 1600°F range.
Type 321 is non hardenable by heat treatment. It can only be hardened by cold working.
