304 has excellent corrosion resistance in a wide variety of environments and when in contact with different corrosive media. Pitting and crevice corrosion can occur in environments containing chlorides. Stress corrosion cracking can occur at temperatures over 60°C.
has good resistance to oxidation in intermittent service up to 870°C and in
continuous service to 925°C. However, continuous use at 425-860°C is not
recommended if corrosion resistance in water is required. In this instance 304L
is recommended due to its resistance to carbide precipitation.
