Material Notes:
Austenitic Cr-Ni stainless steel. More corrosion resistant than Type 301 and because of higher Ni content does not work harden as quickly as Type 301. Essentially non-magnetic in annealed condition, slightly magnetic in cold worked condition. Can be stamped, blanked, formed, and lightly drawn. Applications include car and radar antennas, automobile trim, bottling machinery, dairy processing equipment, food processing equipment, home appliances, hospital equipment, industrial floor plate, jewelry, kitchen and restaurant equipment, spring clips, washers, retainers.
