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. Gibbs 302/304 stainless steel wire is available in the size range of .006″ to .625″. Sizes above and below, upon request. All wire conforms to ASTM A313 and AMS 5688. Type 302 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. Gibbs soap coated Type 302 stainless steel wire is available in the size range 0.014" to 0.625". All wire conforms to ASTM-A-313 and AMS-5688. For more information, view our 302/304 data sheet
