302/304 Stainless Steel Wire Data Sheet Spring Wire

ASTM A313, AMS 5688, AISI 302, AISI 304, UNS 30200, UNS 30400, AISI 302, AISI 304

302/304 Wire Description

Type 302/304 stainless steel wire is a general purpose stainless alloy typically composed of 18% Chromium and 8% Nickel.  It is most widely used stainless steel wire because of its high corrosion resistance and good tensile strength.  For spring applications it is generally furnished in the cold drawn condition.  Type 302/304 springs have good strength at moderate temperatures up to 500°F.  Type 302/304 is non-magnetic in the annealed condition, however material in the spring condition is slightly magnetic due to the transformation of some martinsite in the drawing operation.  The greater the amount of cold reduction, the higher the degree of magnetism.
