AISI Type 302B Stainless Steel, Cold Finished; wire
Categories:	Metal; Ferrous Metal; Heat Resisting; Stainless Steel; T 300 Series Stainless Steel
Material Notes:	Austenitic Cr-Ni stainless steel. More corrosion resistant than Type 301 and 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.
Key Words:	T302, T 302,302 SS, UNS S30215, ASTM A 580 A580
